The analysis phase of the compiler should operate on individual classes, independently
of the analysis of other classes. The validation that `Component.imports` only
contains standalone entities or NgModules however did happen during the analysis phase,
introducing a dependency on other classes and causing inconsistencies due to ordering
and/or asynchronous timing differences.
This commit fixes the issue by moving the validation to the resolve phase, which occurs
after all classes have been analyzed.

Allows to provide a TestBed option to throw on unknown elements in templates:
```ts
getTestBed().initTestEnvironment(
BrowserDynamicTestingModule,
platformBrowserDynamicTesting(), {
errorOnUnknownElements: true

The default value of `errorOnUnknownElements` is `false`, so this is not a breaking change.

In v14, the partial compilation output of components have changed in a way
that prevents older versions of Angular to compile the partial declarations
correctly.
In particular, we used to emit used directives/components in separate arrays called
`components` and `directives`, and used pipes in a property called `pipes`:
```js
TestComponent.ɵcmp = i0.ɵɵngDeclareComponent({
minVersion: "12.0.0",
version: "13.3.0",
type: TestComponent,
selector: "ng-component",
ngImport: i0,
template: ``,
isInline: true,
directives: [{ type: i1.SomeDir, selector: "[some-dir]" }],
components: [{ type: i1.SomeCmp, selector: "some-cmp" }],
pipes: { 'async': i2.AsyncPipe },
});
```
In the above example, the `version` property indicates which exact compiler
version was used to compile the component, but the `minVersion` allows older
versions of the compiler/Angular linker to "link" the partial declaration to
its final AOT compilation output.
In v14, the used directives, components and pipes are now emitted together
into a single array under the `dependencies` property:
```js
TestComponent.ɵcmp = i0.ɵɵngDeclareComponent({
minVersion: "12.0.0",
version: "13.3.0",
type: TestComponent,
selector: "ng-component",
ngImport: i0,
template: ``,
isInline: true,
dependencies: [
{ kind: "directive", type: i1.SomeDir, selector: "[some-dir]" },
{ kind: "component", type: i1.SomeCmp, selector: "some-cmp" },
{ kind: "pipe", type: i2.AsyncPipe },
],
});
```
This change has been made in support of standalone components, but it does mean
that older compiler versions can no longer link these partial declarations
as desirable as none of the components, directives and pipes would be included
in the AOT-compiled code.
By increasing the `minVersion` property, we hint to older compiler versions that
they are not capable of processing the partial declaration. This allows reporting
an error at compile time instead of resulting in runtime failures due to missing
components, directives and pipes.

Update CLDR, which is used to generate the locales files, to version 41.
Also, make necessary code changes to account for changes in the CLDR
data.
Fixes#43301
PR Close#45714
While generating locales, two sets of data (both derived from the
[CLDR project][1]) are used:
- JSON data with the [`cldrjs` package][2], which is used for most
operations.
- XML data with the [`cldr` package][3], which is used for generating
plural-related data.
The JSON data is brought in from the [unicode-org/cldr-json][4]
repository. Since we control the version of the repository that we use,
we can control the CLDR version that these correspond to.
Previously, however, we used the XML data that were bundled with the
[`cldr` package[3]. As a result, the two sets of data could correspond
to different CLDR versions, resulting in incorrect/inconsistent locales
files.
This commit addresses the problem by utilizing the `load()` method of
the [`cldr` package][3], which allows passing in a custom path to the
CLDR XML data (instead of using the bundled data. This way, we can
ensure that the data used for all operations correspond to the same CLDR
version.

Previously, some functions/targets related to the
generation/verification of the `closure-locale.ts` file included
`closure_locales` instead of `closure_locale` in their name, which was
inconsistent and confusing.
Rename all tooling to use `closure_locale` (which more closely matches
the generated file's name).

Adds support for TypeScript 4.7. Changes include:
* Bumping the TS version as well as some Bazel dependencies to include https://github.com/bazelbuild/rules_nodejs/pull/3420.
* Adding a backwards-compatibility layer for calls to `updateTypeParameterDeclaration`.
* Making `LView` generic in order to make it easier to type the context based on the usage. Currently the context can be 4 different types which coupled with stricter type checking would required a lot of extra casting all over `core`.
* Fixing a bunch of miscellaneous type errors.
* Removing assertions of `ReferenceEntry.isDefinition` in a few of the language service tests. The field isn't returned by TS anymore and we weren't using it for anything.
* Resolving in error in the language service that was caused by TS attempting to parse HTML files when we try to open them. Previous TS was silently setting them as `ScriptKind.Unknown` and ignoring the errors, but now it throws. I've worked around it by setting them as `ScriptKind.JSX`.

Ensure that keyframes rules, defined within components with emulated
view encapsulation, are scoped to avoid collisions with keyframes in
other components.
This is achieved by renaming these keyframes to add a prefix that makes
them unique across the application.
In order to enable the handling of keyframes names defined as strings
the previous strategy of replacing quoted css content with `%QUOTED%`
(introduced in commit 7f689a2) has been removed and in its place now
only specific characters inside quotes are being replaced with
placeholder text (those are `;`, `:` and `,`, more can be added in
the future if the need arises).
Closes#33885
BREAKING CHANGE:
Keyframes names are now prefixed with the component's "scope name".
For example, the following keyframes rule in a component definition,
whose "scope name" is host-my-cmp:
@keyframes foo { ... }
will become:
@keyframes host-my-cmp_foo { ... }
Any TypeScript/JavaScript code which relied on the names of keyframes rules
will no longer match.
The recommended solutions in this case are to either:
- change the component's view encapsulation to the `None` or `ShadowDom`
- define keyframes rules in global stylesheets (e.g styles.css)
- define keyframes rules programmatically in code.

There were two problems with the `importProvidersFrom` function related to
`ModuleWithProviders` values:
* The public type did not accept `ModuleWithProviders` values directly.
* The implementation of `walkProviderTree` delegates collection of MWP providers
to its caller, in order for the ordering of such providers to be correct.
However, `importProvidersFrom` was not performing that collection, causing MWP
providers passed in at the top level to be dropped.
