There are legitimate cases where access to an EnvironmentInjector
of a bootstrapped application is required / convenient. It will be also
required for support of standalone components with Angular elements.
PR Close#46665
`BootstrapOptions` is exposed through `PlatformRef#bootstrapModule` but
is not included in the public API so you cannot find it on angular.io.
This commit simply marks the interface as public API (as it should be).

This change adds the setInput method to the ComponentRef.
Previously users had to call `componentRef.instance['inputName']`
to change inputs of a dynamically created component. This had
several problems:
* OnPush components were not marked for check and thus very
difficult to test;
* input aliasing was not take into account - a property name
on a component could have been different from the actual input
name so setting input properties was fragile;
* manually setting input propertie would NOT trigger the
`NgOnChanges` lifecycle hook.
This modifications unifies `@Input` accross dynamically created
components and the ones referenced in templates. This also opens
doors to other changes: as an example router could use this new
method to set `@Input`s from router params.

`inject()` originated as a private API and was made public to support
`InjectionToken` factories in Ivy. For code-size and performance reasons,
when we code generate `inject()` calls we use a bit field to indicate the
various injection modes (optional, skip-self, etc). However, this doesn't
make for a very nice public API.
This commit introduces an alternative object-based API for options. All 4
flags are supported as `boolean` fields on an options object, and converted
to bit flags internally. If TypeScript can prove that `optional` injection
is not requested, it can narrow the return type and remove the `null` type.
DEPRECATED:
The bit field signature of `inject()` has been deprecated, in favor of the
new options object. Correspondingly, `InjectFlags` is deprecated as well.

The test apps are bundled using their production ESM JS output using
`esbuild`. ESBuild warns about any CJS usages, like `module.exports.`
```
INFO: From Bundling Javascript packages/core/test/bundling/todo_i18n/index.ts [esbuild]:
▲ [WARNING] The CommonJS "module" variable is treated as a global variable in an ECMAScript module and may not work as expected
bazel-out/k8-fastbuild/bin/packages/core/test/bundling/todo_i18n/index.mjs:494:0:
494 │ module.exports = {

This file is considered to be an ECMAScript module because the file name ends in ".mjs".
```
Some bundling tests currently use `module.exports` to make
functions/symbols available to specs later requiring the bundle (in
order to run the bundle). Instead of using the CJS global here, the
logic can be attached consistently to `window` (there is currently a
mismatch of window vs. module.exports anyway..).

The Angular CLI has removed the JSON5 parsing and now always uses
`jsonc-parser`. Our test checks if JSON5 features can be parsed, but
this now breaks and the test needs to be adjusted.
We still want to keep the test to ensure we do not parse the Angular
CLI workspace file in a different way, not e.g. supporting jsonc.

This commit introduces a new API on `EnvironmentInjector` to run a function
in the context of the injector. This makes `inject()` available within the
body of the function to inject dependencies. We expect this functionality to
be very useful for designing ergonomic APIs both in and out of Angular, as
it should allow for a smaller and more functional API style.
Note that it's possible to implement nearly identical functionality in user
code already today:
```typescript
function runInContext<T>(injector: EnvironmentInjector, fn: () => T): T {
const token = new InjectionToken<T>('TOKEN');
const tmpInjector = createEnvironmentInjector([
{provide: token, useFactory: () => fn()},
], injector);
return tmpInjector.get(token);
}
```
The factory provider for `token` in this example runs in the context of the
`tmpInjector`, giving it access to `inject` that can retrieve values from
`injector` as well. This is nearly identical, although because of the child
injector `self` and `skipSelf` injection options don't function correctly.

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.
PR Close#46605
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.
PR Close#46605
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.

Remove calls to enableRenderer3 in the functional unit tests.
This effectivelly cuts code paths going through the Renderer3

PR Close#46612
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.
