This commit removes the experimental `renderComponent` operation, which
implemented an alternative, lighter-weight bootstrapping option. This
experiment is being discontinued as the path towards it being a supported
production API was not clear. In particular, it lacked a clear roadmap for
supporting Angular's change detection, particularly when consuming existing
components.

This commit removes the `Renderer3` experiment which attempted to use the
real DOM API as Angular's renderer. As shown in the diff, having this
experiment around added real code complexity to Angular that could not be
removed by an optimizer.
Since we no longer feel this experiment is worth continuing, we're removing
the `Renderer3` concept and all supporting code.

Previously, when instantiating a component, Angular would look in the DI
hierarchy for `RendererFactory2`. Any DI tree which rolls up through an
application injector (that is, one created with `BrowserModule`) should be
able to provide this interface. If not found, Angular would switch to the
experimental `Renderer3` mechanism. This switch was designed this way,
because it allowed for the creation of experimental applications where
`RendererFactory2` was not included in the bundle at all.
In this commit, instead of automatically falling back on `Renderer3`-style
rendering, an error is raised instead if `RendererFactory2` is missing from
the DI hierarchy.

This commit migrates any remaining Angular tests which are using some form
of Renderer3 interfaces. Instead, they're switched to Renderer2.
PR Close#46605
Due to the restrictions of circular dependency checking, we need a separate
internal interface for a renderer. We cannot use `Renderer2` as a type
internally as even importing it as a type incurs a dependency on its
implementation, which creates a major potential for circular dependencies.
Previously this role was served by the `Renderer3` type. As we prepare to
remove the `Renderer3` abstraction (the idea of using `document` as a
differently-shaped renderer), this commit renames `ProceduralRenderer3` to
the more generic term `Renderer`.
`RendererFactory3` is also renamed to the more generic `RendererFactory` for
consistency.

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).

The `hello_world` and `todo` bundling tests use the experimental
`renderComponent` function (and `Renderer3`) as a result, and have

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 commit updates a set of tests to avoid using hand-written instructions and replace them with TestBed APIs. Some tests were moved to the `acceptance` folder to colocate them with other renderer-related tests.

di_spec.ts was using handwritten definitions and the `renderComponent`-based

This commit updates it to:
* remove unnecessary tests ("limp mode" DI, Renderer3, etc)
* convert other tests to use JIT-compiled classes and not handwritten defs

This commit convers the providers_helper utility function
`expectProvidersScenario` to use the TestBed internally instead of
`ComponentFixture` and handwritten defs. This required several adjustments:
* Making the `ngModule`s passed in to the helper utility real NgModules.
* Using `ViewEncapsulation.None` for the test components (stabilizes the
generated HTML).
* Convert handwritten test components & directives into JIT-compiled
standalone equivalents.

Currently, when importing `BrowserAnimationsModule`, Angular provides
`AnimationRendererFactory` as the `RendererFactory2`. The `AnimationRendererFactory`
relies on the `AnimationEngine`. The `AnimationEngine` may be created earlier than the
`ApplicationRef` (e.g. if it's requested within the `APP_INITIALIZER` before the `ApplicationRef`
is created). This means that Angular will add the `AnimationEngine` to `R3Injector.onDestroy`
before the `ApplicationRef`. The `R3Injector` will call `ngOnDestroy()` on the `AnimationEngine`
before the `ApplicationRef`, which means the `flush()` will be called earlier before views are destroyed.

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.

Prior to standalone components, the `applyProviderOverridesToModule` method was used exclusively for NgModules. With standalone, its scope was expended to include standalone components as well. This commit renames the method to `applyProviderOverridesInScope` to better reflect this + also renames a field that refers to a set that contains already overridden types.

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.
