When setting up an async validator in a template-driven form, it's necessary to register the directive with NG_ASYNC_VALIDATORS instead of NG_VALIDATORS. This was not mentioned in the docs.

Add a new option for configuring data-groups, `cacheOpaqueResponses`,
that determines whether opaque responses are cached or not. This allows
greater flexibility in configuring the behavior of data-groups, while
still keeping the current defaults as fallbacks.
Fixes#44246

Make the `MockResponse` class used in tests behave more similarly to how
real responses work by making the following improvements:
- Use an empty `statusText` (`''`) when provided, instead of the default
`'OK'` value. This allows better representing opaque responses.
- Preserve more properties (`redirected`, `type`, `url`) when cloning a
`MockResponse`.

The previous fix for correcting spans with comments in
59eef29a6c
had the unfortunate side effect of _breaking_ the spans with comments
when there was leading whitespace. This happened because the previous
fix was testing one without a comment, identifying that the offset shouldn't
have anything added to it, and then removing that offset adjustment
(`offsets[i] + (expressionText.length - sourceToLex.length)`).
Upon further investigation, this offset adjustment _was actually
necessary_ for when the input had comments, but this was only because
the `stripComments` function used `trim` to remove whitespace for these
cases. This is the real problem -- not only does it create a ton of confusion
but also it means that the behavior of the lexer and resulting spans is
different between inputs with comments and inputs without comments.
After reviewing how the `inputLength` of `_ParseAST` was used, it
appears that the correct behavior would be to _not_ trim the input. The
`inputLength` is used to advance the current index beyond points which
have been processed. This _should_ include any whitespace. Additionally,
`inputLength` doesn't appear to be needed at all. When there was no
comment in the input, it was always equal to the `input.length` anyways.
When there _is_ a comment, it should include that comment anyways to
advance the index beyond the comment.

When running tests with code coverage using Istanbul, the code is
instrumented with coverage reporting statements. These statements are
also inserted into synthesized constructors, preventing Angular from
properly recognizing them as synthesized constructor.
This commit changes the regex to detect synthesized constructors to allow
for statements within the constructor before the `super(...arguments);`
call. This is limited to code that does not contain a `}`, but this
is sufficient to support Istanbul's coverage instrumentation statements.
The tests have been extended with an input file that is being
instrumented using `babel-plugin-istanbul` for both ES2015 and ES5
targets, in order to verify that the approach works for real-world
usages.

Error: error NG4004: Angular compiler option "extendedDiagnostics.checks['invalidBananaInBox']" has an unknown diagnostic category: "test".
Allowed diagnostic categories are:
warning
error
suppress
```
The assertion comes from `ExtendedTemplateCheckerImpl`, which expects a well-formed configuration, yet the compiler would construct it even when errors were found. This commit skips constructing and running extended diagnostics if the configuration had errors, which should avoid triggering these assertion errors.
I'm unfortunately not able to actually test this change. The test passes even before the fix because the `ngc` binary and end-to-end tests [don't request diagnostics unless the configuration is considered valid](ed21f5c753/packages/compiler-cli/src/perform_compile.ts (L292-L293)). See [Slack](https://angular-team.slack.com/archives/C4WHZQMRA/p1642641305003800) for more details.

`Renderer2` APIs expect to be called with the namespace name rather than
the namespace URI. Rather than passing around the URI and having to
account for different calling contexts, this change consistently uses
the namespace short names.
Importantly, the URI was only used in `component_ref.ts` `create`
(because `getNamespace returned the URIs`) and `createElementNode` in
`node_manipulation.ts` (because `getNamespaceUri` also used the URIs).
In contrast, attributes would use the _short names instead of URIs_
(see `setUpAttributes` in `attrs_utils.ts`). These names are pulled
directly from the attribute, i.e. `xhtml:href` and not converted to URI.
This dichotomy is confusing and unnecessary. The change here aligns the two
approaches in order to provide consistently throughout the system.
This relates to #44766 because the `createElementNode` was calling the
`AnimationRenderer.createElement` which delegates to the
`ServerRenderer`, which in turn was only set up to expect short names.
As a result, the `NAMESPACE_URIS` lookup failed and `Domino` created
the `svg` as a regular `Element` which does not have a `styles`
property.

When the user wants to rename a symbol in the ts file VSCode
will ask the rename providers for the answer in turn. If the
first extension returns the result, the VSCode will break the
loop and apply the result. If the first extension cannot rename
the symbol, VSCode will ask the second extension in the
list (built-in TS/JS extension, Angular LS extension, etc.).
In other words, VSCode takes the result from only one rename provider
and the order depends on registration timing, scoring.
Because the built-in ts extension and Angular extension have the
same high score, if the built-in ts extension is the
first(depends on the time the extension was registered), the result
will be provided by the built-in extension. We want Angular to
provide it, so this plugin will delegate rename requests and reject
the request for the built-in ts server.
The Angular LS only provides the rename info when working within
an Angular project. If we cannot locate Angular sources in the
project files, the built-in extension should provide the rename info.
This plugin will apply to the built-in TS/JS extension and delegate
rename requests to the Angular LS. It provides the rename info only
when it is an Angular project. Otherwise, it will return info by the
default built-in ts server rename provider.
See [here][1] for more info.

Extended diagnostics provide additional analysis about Angular templates by emitting warnings for specific patterns known to be error prone or cause developer confusion. Currently, there are two such diagnostics which are enabled by default:
* `invalidBananaInBox` emits a warning if a user writes a two-way binding backwards like `([foo])="bar"`, when they actually wanted `[(foo)]="bar"`.
* `nullishCoalescingNotNullable` emits a warning if a binding attempts to perform nullish coalescing (`??`) on a type which does not include `null` or `undefined`, such as `{{ foo ?? 'bar' }}` where `foo` is defined as `string` instead of `string | null`.
These diagnostics are enabled as warnings by default, but this can be configured in the `tsconfig.json` like so:
```jsonc
{
"angularCompilerOptions": {
"extendedDiagnostics": {
// The categories to use for specific diagnostics.
"checks": {
// Maps check name to its category.
"invalidBananaInBox": "suppress"
},
// The category to use for any diagnostics not listed in `checks` above.
"defaultCategory": "error"
}
}
}
```
Allowed categories for a diagnostic are `warning` (default), `error`, or `suppress`. `warning` emits the diagnostic but allows the compilation to succeed, `error` *will* fail the compilation, while `suppress` will ignore the diagnostic altogether.
The initial release has two diagnostics, and we are hoping to expand this longer term to add more diagnostics and provide additional insight into Angular templates to detect and surface developer mistakes *before* hours of debugging are wasted.

The directive matching pass that happens during template compilation is
redundant, since directive matching has already happened during the resolution
phase of ngtsc and only matching declarables are provided to the template
compiler. In JIT mode the declarables only become available after the primary
template compilation has completed, so there is no need to perform directive
matching in both JIT and AOT mode.
