Making the typing filtering more explicit allows typescript to properly recognize the presence of the
`prototype` property on the provider within the `registerDestroyHooksIfSupported` method.

Prior refactorings caused unexpected g3 sync issues due to a patch that
changes the error documentation URL. This commit moves the base url into
a separate file to make this more apparent.
PR Close#43527
The `ErrorCode` enum in the `error_code.ts` file is governed by public
api guards but the other top-level exports from that file are exempt
from public api documentation and are therefore marked as `@internal`.
However, TypeScript is configured with the `stripInternal` compiler
option such that declarations with `@internal` markers are not emitted
into the `.d.ts` files, but this means that the reexports in the barrel
file end up referring to missing declarations.
The `stripInternal` option is considered internal and its documentation
states to use at your own risk (as per https://github.com/microsoft/TypeScript/issues/45307).
Having the option enabled is desirable for us as it works well for
hiding class fields that are marked `@internal`, which is an effective
way to hide members from the .d.ts file. As a workaround for the issue
with top-level symbols, the declarations with `@internal` markers are
moved to dedicated files for which no public api guard is setup,
therefore allowing their `@internal` markers to be dropped.

Setting the angular_ivy_enabled environment variable to True will default Bazel builds to use the Ivy
compiler rather than defaulting to ViewEngine.
PR Close#43862
DEPRECATION:
In ViewEngine, [JIT compilation](https://angular.io/guide/glossary#jit) required special providers (like `Compiler`, `CompilerFactory`, etc) to be injected in the app and corresponding methods to be invoked. With Ivy, JIT compilation takes place implicitly if the Component, NgModule, etc have not already been [AOT compiled](https://angular.io/guide/glossary#aot). Those special providers were made available in Ivy for backwards-compatibility with ViewEngine to make the transition to Ivy smoother. Since ViewEngine is deprecated and will soon be removed, those symbols are now deprecated as well:
- `ModuleWithComponentFactories`
- `Compiler`
- `CompilerFactory`
- `JitCompilerFactory`
- `NgModuleFactory`
Important note: this deprecation doesn't affect JIT mode in Ivy (JIT remains available with Ivy).
PR Close#43710
NgModule factories are obsolete with Ivy and most of the operations can already be performed with NgModule classes without retreieving corresponding factories. NgModule factories were useful to generate an `NgModuleRef` (via `NgModuleFactory.create` method). This commit adds a new function to create an instance of the `NgModuleRef` class without having the need to create a factory first.
PR Close#43580
This commit adds a new function called `getNgModuleById` to the public API surface of the framework. The `getNgModuleById` function allows to retrieve loaded NgModule class by id (specified via `@NgModule.id`). The function is a replacement for the `getModuleFactory` function.
DEPRECATION:
The `getModuleFactory` function is deprecated in favor of the `getNgModuleById` one. With Ivy it's possible to work with NgModule classes directly, without retrieving corresponding factories, so the `getNgModuleById` should be used instead.

Internally, g3 code still uses the `loadChildren: string` syntax. We
need to continue to provide this functionality with an internal patch.
This change makes that patch easier by only touching stub files that

After updating to a more recent version of rollup, rollup started to
complain because the `inject` and `ɵɵinject` functions are being re-exported
twice in the `@angular/core` public API entry-point.
Rollup threw errors like:
```
[!] Error: “ɵɵinject” cannot be exported from node_modules/@angular/core/esm2015/src/di/injector_compatibility.js as it is a reexport that references itself.
```
A similar error is shown for `CodegenComponentFactoryResolver`.
It seems like Rollup ideally would not throw here, similar to TypeScript
which detects that these exports are the same and just dedupes them, but
it's low-effort fixing this for now.

BREAKING CHANGE:

libraries are used that are still using `WrappedValue`. The usage of
`WrappedValue` should be removed as no replacement is available.

This commit removes the ability to configure lazy routes using a string
for `loadChildren`, together with the supporting classes to load an
`NgModuleFactory` at runtime.
BREAKING CHANGE:
It is no longer possible to use `Route.loadChildren` using a string
value. The following supporting classes were removed from
`@angular/core`:
- `NgModuleFactoryLoader`
- `SystemJsNgModuleFactoryLoader`
The `@angular/router` package no longer exports these symbols:
- `SpyNgModuleFactoryLoader`
- `DeprecatedLoadChildren`
The signature of the `setupTestingRouter` function from
`@angular/core/testing` has been changed to drop its `NgModuleFactoryLoader`
parameter, as an argument for that parameter can no longer be created.

With Ivy it's possible to create a `ComponentFactory` instance based on the generated Component def, thus the `ViewContainerRef.createComponent` can accept a Component instance and create a factory inside, rather than requiring additional complexity of creating a ComponentFactory outside (by invoking `ComponentFactoryResolver`).
This should simplify the API that is used for creating components dynamically.
DEPRECATION:
Angular no longer requires component factories to dynamically create components. The factory-based signature of the `ViewContainerRef.createComponent` function is deprecated in favor of a different signature that allows passing component classes instead.
PR Close#43022
DEPRECATION:
Ivy made it possible to avoid the need to resolve Component and NgModule factories. Framework APIs allow to use Component and NgModule Types directly. As a result, the `PlatformRef.bootstrapModuleFactory` and a factory-based signature of the `ApplicationRef.bootstrap` method are now obsolete and are now deprecated.
The `PlatformRef.bootstrapModuleFactory` calls can be replaced with `PlatformRef.bootstrapModule` ones. The `ApplicationRef.bootstrap` method allows to provide Component Type, so this can be used a replacement for the factory-based calls.

Adds support for TypeScript 4.4. High-level overview of the changes made in this PR:
* Bumps the various packages to `typescript@4.4.2` and `tslib@2.3.0`.
* The `useUnknownInCatchVariables` compiler option has been disabled so that we don't have to cast error objects explicitly everywhere.
* TS now passes in a third argument to the `__spreadArray` call inside child class constructors. I had to update a couple of places in the runtime and ngcc to be able to pick up the calls correctly.
* TS now generates code like `(0, foo)(arg1, arg2)` for imported function calls. I had to update a few of our tests to account for it. See https://github.com/microsoft/TypeScript/pull/44624.
* Our `ngtsc` test setup calls the private `matchFiles` function from TS. I had to update our usage, because a new parameter was added.
* There was one place where we were setting the readonly `hasTrailingComma` property. I updated the usage to pass in the value when constructing the object instead.
* Some browser types were updated which meant that I had to resolve some trivial type errors.
* The downlevel decorators tranform was running into an issue where the Closure synthetic comments were being emitted twice. I've worked around it by recreating the class declaration node instead of cloning it.

Introduce two new bazel rules: tsec_test and tsec_config, for
describing the tsec checks and the tsconfig file needed for such
checks, respectively. Currently, tsec_test only checks the srcs
of a ts_library or ng_module. It does not check direct or transitive
dependencies. Also, tsconfig files need to be manually maintained
to make sure tsec can read all necessary input (including global
symbols).

Class static properties with initializers that cause code execution (for example, call expressions or new expressions) have the potential to cause side effects at module evaluation. This is similar in effect to module level code. As a result, optimizers can not safely remove a class with such a static property as the potential side effects may have meaningful effects on the state of the application execution. To allow classes with these type of static properties to be optimized and removed if unused, the initializer expressions for the static properties can be annotated as pure. This annotation provides a signal to an optimizer that the expression does not have any potential side effects and is useful in cases where static analysis can not currently prove that there are, in fact, no side effects caused by the initializer.

It is necessary in order to distinguish 2 different reasons for referencing the compiled-in locale.
1. Some code just needs to pass the locale value on to logic that actually uses it.
2. Other code uses the locale value to select locale-specific user-visible data and behavior.
Code modified by this change is of the first kind and should use `goog.getLocale()` in the future.
Note: there are still references to the `goog.LOCALE` in Angular codebase, but they are of second type.

Currently if a view throws an error during creation mode, we mark it as `incompleteFirstPass` so that we can try to recover later. The recovery is only possible inside component views.
The problem is that when this was introduced, I forgot to flip the `firstCreatePass` when an error is thrown which meant that calling `renderView` on the same component again is allowed. It will eventually hit an assertion which can be confusing for the end user. This issue only manifests itself when rendering views "manually" through `ViewContainerRef` (e.g. using `NgIf`).
These changes flip the `firstCreatePass` back to false on errors so that trying to re-render the same view will throw an error which is consistent to the one that broke the view during creation.

If a decorator or partial declaration has not been AOT compiled, then
the compiler is needed at runtime to be able to JIT compile the code.
However, it may occur that the compiler is not available, if it has not
been loaded into the application. The error that was reported in this
case did not provide insight into which class requested compilation, nor
did it differentiate between decorators vs. partial declarations.
This commit expands the error logging to provide better insight into the
class that initiated JIT compilation and offers a specialized error
message for partial declarations. This should help a developer better
understand why the error occurs and what can be done to resolve it.

In #41995 the type of `TrackByFunction` was changed such that the
declaration of a `trackBy` function did not cause the item type to be
widened to the `trackBy`'s item type, which may be a supertype of the
iterated type. This has introduced situations where the template type
checker is now reporting errors for cases where a `trackBy` function is
no longer assignable to `TrackByFunction`.
This commit fixes the error by also including the item type `T` in
addition to the constrained type parameter `U`, allowing TypeScript to
infer an appropriate `T`.
