This commit converts the remaining bundling tests which were using
`renderComponent` to use regular bootstrapping instead.
Since `renderComponent` is synchronous and regular bootstrapping is not,
some test adjustments were necessary to wait for bootstrapping before test
assertions could run.
Additionally, debug servers were adjusted in some cases where they'd broken
(likely some time ago).

Replace `new Error()` in a forms Validators function with `RuntimeError`, for better tree-shakability. Also, improve the error messages, and add documentation.
PR Close#46537
The `Renderer3` abstraction in Angular was an experimental code path in Ivy
which uses direct DOM operations instead of the former `Renderer2` path. To
allow `Renderer2` to tree-shake away, `Renderer3` is the default _unless_
`Renderer2` is provided. It was only an experiment, and never meant to be a
production code path.
However, it's possible for `Renderer3` to leak into user code. This commit
prevents that possibility by causing the `Renderer3` path to throw, unless
an explicit function has been called to enable it.

This change separates the router initializer into different providers.
While it does not actually change the tree-shakeablity or the public
API, it does move us towards a world that _could_ do this. That is,
instead of `initialNavigation: 'disabled'`, users could use
`provideDisabledInitialNavigation` in the `bootstrapApplication` call
and none of the code for `initialNavigation: 'enabledBlocking'` would be
included in the application.

Extracting preloading to a provider moves us towards
thinking about a world where `ExtraOptions` doesn't exist to control
behaviors that are opt-in/opt-out. Instead, these behaviors could be
controlled by the presence (or lackthereof) of the providers which has
the functionality. This is relevant to a world in which we no longer
have the `RouterModule` but instead have something like `provideRouter`
where the features are tree-shakeable.
This change _does not_ make the `RouterPreloader` tree-shakeable inside
`RouterModule.forRoot` because the compiler cannot statically determine
whether it's needed. However, in the `provideRouter` world without
`forRoot`, preloading could be exposed through the provider function
instead, making the `RouterPreloader` and `PreloadingStrategy`
implementations tree-shakeable for those that don't use it (which is the
default - no preloading).

During JIT compilation of standalone components the compiler did not deduplicate
declarations in the imports array, unlike the AOT compiler. This may result in
runtime errors during directive matching, when the same component is found
multiple times resulting in NG0300, for example:
> NG0300: Multiple components match node with tagname mat-form-field: MatFormField and MatFormField.
This commit fixes the issue by deduplicating imports in the JIT compiler.

Prior to this commit, the TestBed logic erroneously tried to apply provider overrides to standalone pipes that were imported in an NgModule. This commit updates the logic to recognize types that may have a scope (an NgModule or a standalone component) and skip other types while applying provider overrides recursively.

Previously, the `createEnvironmentInjector` function allowed creating an instance of an EnvironmentInjector without providing a parent injector. This resulted in an injector instance, which was detached from the DI tree, thus having limited value. This commit updates the types of the `createEnvironmentInjector` function to make the parent injector a required argument.

The `Observable` chain is currenlty the most straightforward way to
handle navigation cancellations where we ensure that the cancelled
navigation does not continue to be processed. Until we design and
implement an alternative way to accomplish equivalent functionality,
we need to maintain the `Observable` chain wherever we might execute
user code. One reason for this isthat user code may contain redirects so we do not
want to execute those redirects if the navigation was already cancelled.

Consider the case in which `FormBuilder` is used to construct a group with an optional field:
```
const controls = { name: fb.control('') };
const foo: FormGroup<{
name: FormControl<string | null>;
address?: FormControl<string | null>;
}> = fb.group<{
name: FormControl<string | null>;
address?: FormControl<string | null>;
}>(controls);
```
Today, with fully strict TypeScript settings, the above will not compile:
```
Types of property 'controls' are incompatible.
Type '{ name: FormControl<string | null>; address?: FormControl<FormGroup<SubFormControls> | null | undefined> | undefined; }' is not assignable to type '{ name: FormControl<string | null>; address?: FormGroup<SubFormControls> | undefined; }'.
```
Notice that the `fb.group(...)` is calculating the following type for address: `address?: FormControl<FormGroup<string|null>`. This is clearly wrong -- an extraneous `FormControl` has been added!
This is coming from the calculation of the result type of `fb.group(...)`. In the type definition, if we cannot detect the outer control type, [we assume it's just an unwrapped value, and automatically wrap it in `FormControl`](https://github.com/angular/angular/blob/14.0.0/packages/forms/src/form_builder.ts#L66).
Because the optional `{address?: FormControl<string|null>}` implicitly makes the RHS have type `FormControl<string|null>|undefined`, [the relevant condition is not satisfied](https://github.com/angular/angular/blob/14.0.0/packages/forms/src/form_builder.ts#L55). In particular, the condition expects just `FormGroup<T>`, not `FormGroup<T>|undefined`. So we assume `T` is a value type, and it gets wrapped with `FormControl`.
The solution is to add the cases where `undefined` is included in the union type when detecting which control `T` is (if any).

the formatted error messages always include a period separator between the

desirable as it may add periods when they shoud not be, so improve the
formatting by checking and applying the period only if the provided message
doesn't end with a character which already represents a separator
additionally also improve the formatting by trimming the provided error
message
note that such trimming needs to be performed before the separator check
so that for example an error message like `"some error! "` doesn't produce
`"some error! ."` but it successfully produces "some error!"

This exposes a new function from the router public API that allows
developers to create a `UrlTree` from _any_ `ActivatedRouteSnapshot`.
The current Router APIs only support creating a `UrlTree` from an
`ActivatedRoute` which is both active _and_ materially appears in the
`UrlTree` (it cannot be an empty path named outlet). This is because the
implementation of the current way of creating a `UrlTree` attempts to
look up the `UrlSegment` of the `ActivatedRoute` in the currently active
`UrlTree` of the router. When this doesn't work, the `UrlTree` creation
fails.
Note that this API does not replace the current one. That would actually be a
breaking change but should be done at some point in the future (v15). That is,
`router.navigate` should call this new function. At that point, we can
remove `_lastPathIndex`, `_urlSegment`, and `_correctedPathIndex` from
the `ActivatedRoute`, along with all of the logic associated with
determining what those should be. In addition, this would unblock a fix
for #26081 because the `applyRedirects` and `recognize` operations
could be combined into one. Overall, this would simplify logic in the router
and reduce code size. It also exposes core routing capabilities as a helper function
which were previously private API, which is a necessary step towards #42953.
As a stress test for this new function, it _was_ swapped in as the
default for `UrlTree` creation in #45859 and tested internally. The
results indicate that this function behaves correctly.

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.
