update the error message presented during aot compilation when an unrecognized
tag/element is found in a standalone component so that it does not mention
the ngModule anymore
Note: the jit variant is present in PR #45920resolves#45818
PR Close#45919
Currently for cases when an unknown structural directive is applied to `<ng-template>`s, an error message thrown by the framework doesn't contain a tag name, for example:
```
NG0303: Can't bind to 'unknownDir' since it isn't a known property of 'null'.
```
The underlying reason is that the tag name for the `<ng-template>` is not produced (`null` is useed as a value) by the compiler in case of inline templates and runtime logic relies on this effect.
This commit handles this situation when an error message is thrown, as the fastest way to improve the error message. More refactoring would be needed to avoid relying on the mentioned effect at runtime.

Previously, the code in TestBed didn't take into account the fact that the `cmp.dependencies` array after the AOT compilation might contain regular (NgModule-based) Components/Directive/Pipes. As a result, some NgModule-specific code paths were invoked for non-NgModule types, thus leading to errors.
This commit updates the code to handle AOT-compiled structure of standalone components correctly.

This commit updates the NgModule logic to account for a case when a type has more than one generated def. This is a common situation for NgModules which have at least two: ɵmod and ɵinj. Previously, the second def was not stored before applying overrides, thus leaving it modified after the test, leaking the state as a result. This fix ensures that we store all defs before applying any overrides.

This commit accounts for the Babel types changes. Some properties
can now also be `undefined` so existing checks/assertions had to
be adjusted to also capture `undefined` (along with `null`).
Additionally, in preparation for a new ECMA proposal, Babel types
seem to have been updated to include private names in object property
keys. This is not necessarily the case for object expressions, but
could be for object patterns (in the future -- when implemented).
More details: https://github.com/babel/babel/pull/14304 and

We recently updated Babel and the Bazel types but this actually
resulted in duplicates, causing differences between what people
seen in their IDE vs. what Bazel builds.
This commit removes the lock file and generates it fully fresh,
deduping dependencies and also fixing the differences between
local IDE and Bazel.
As part of this we also need to update/fixup one assertion on the
Babel node path types, because the node start/end can now also
be `undefined`.

DEPRECATED:
It is now deprecated to provide *both* `AbstractControlOption`s and an async validators argument to a FormControl. Previously, the async validators would just be silently dropped, resulting in a probably buggy forms. Now, the constructor call is deprecated, and Angular will print a warning in devmode.
DEPRECATED:
The `initialValueIsDefault` option has been deprecated and replaced with the otherwise-identical `nonNullable` option, for the sake of naming consistency.
In some places, the [@see][1] JSDoc tag was incorrectly used instead of
the [@link][2] inline tag, leading to warnings during doc generation and
the `@see` tags being ignored (and thus shown in the docs as is).
Replace the `@see` tags with the intended `@link` tags.

Adds additional tests to verify `enabledBlocking` functionality. The
initial attempt to fix#44355 would have broken the scenario where a new
navigation cancels the initial navigation. We also cannot rely on
`NavigationError` like the example workaround in that issue report is
doing because there won't be one if a guard simply rejects
the initial nav (#16211).

This commit fixes a small issue in the logic around the calculation of
template scopes for standalone components. These scopes include a
`Reference` for each dependency of a standalone component, which is used to
generate references to that dependency in various contexts.
Previously, the `Reference` used for a dependency was the one generated from
its own metadata. For example, a referenced directive used the `Reference`
that was created when analyzing the directive declaration itself. This still
works, as the compiler is always able to emit a reference to any valid
`Reference`. However, it's not optimal.
The `Reference` which should be used instead is the one generated from
analyzing the standalone component's `imports` array, which has knowledge of
how the dependency is referenced from within the standalone component's file
itself. This allows the compiler to skip creating a new import for the
dependency when emitting the standalone component, and use the existing,
user-authored import instead. This saves on code size and avoids taxing the
bundler with unnecessary imports.
PR Close#46029
The Angular compiler performs cycle detection when generating imports within
component files. This was previously necessary as reifying dependencies
discovered via NgModules into the component output could add imports that
weren't present in the original component and potentially create cycles.
Doing this could cause order-of-execution issues with existing user imports,
so the compiler detects this case and falls back to an alternative way of
specifying component dependencies that doesn't risk creating cycles.
For standalone components, Angular does not need to add new imports to the
component file as the user has already explicitly referenced dependencies
in the `@Component.imports`. As a result, the cycle detection can be
skipped.
Correctly authoring a program with import cycles is always challenging. One
side of a cyclic import will always initially evaluate to `undefined`, and
this can result in errors in the component definition when this happens
within component `imports`.
Our compiler _could_ detect the cycle and choose to wrap the component
dependencies in an automatic closure instead, avoiding any issues with
`undefined` during an eager evaluation. However, this commit makes an active
choice not to do that as it only serves to mask the problems with cyclic
imports. Future refactorings may cause the "other half" of the cycle to
break. Users should instead be aware of the potential problems with cycles
and explicitly defer evaluations with `forwardRef` where needed. This
ensures that future implementations of Angular compilation which may not be
able to automatically detect import cycles and correct accordingly can still
compile such components.

Consider a typed group for storing contact information:
```
declare interface ContactControls {
name: FormControl<string|null>;
}
contactForm: FormGroup<ContactControls> = ...;
saveForm(form: FormGroup<ContactControls>) {
service.newContact(contactForm.value);
}
```
What should be the type of `newContact`? The answer, of course, is the value type:
```
declare interface Contact {
name: string|null;
}
class ContactService {
newContact(c: Contact) {}
}
```
This is quite redundant, and therefore, we should allow the value type to be generated automatically. We already have the helper types to do this -- we just need to document and export them. Then, this becomes possible:
```
class ContactService {
newContact(c: RawValue<FormGroup<ContactControls>>) {}
}
```
