Previously, the compiler was not able to display template parsing errors as
true `ts.Diagnostic`s that point inside the template. Instead, it would
throw an actual `Error`, and "crash" with a stack trace containing the
template errors.
Not only is this a poor user experience, but it causes the Language Service
to also crash as the user is editing a template (in actuality the LS has to
work around this bug).
With this commit, such parsing errors are converted to true template
diagnostics with appropriate span information to be displayed contextually
along with all other diagnostics. This majorly improves the user experience
and unblocks the Language Service from having to deal with the compiler
"crashing" to report errors.

The template type-checking engine includes utilities for creating
`ts.Diagnostic`s for component templates. Previously only the template type-
checker itself created such diagnostics. However, the template parser also
produces errors which should be represented as template diagnostics.
This commit prepares for that conversion by extracting the machinery for
producing template diagnostics into its own sub-package, so that other parts
of the compiler can depend on it without depending on the entire template
type-checker.

`tView` that is stored on a component def contains information about directives and pipes
that are available in the scope of this component. Patching component scope causes `tView` to be
updated. Prior to this commit, the `tView` information was not restored/reset in case component
class is not declared in the `declarations` field while calling `TestBed.configureTestingModule`,
thus causing `tView` to be reused between tests (thus preserving scopes information between tests).
This commit updates TestBed logic to preserve `tView` value before applying scope changes and
reset it back to the previous state between tests.
Closes#38600.

Previously this package was installed in the default `dependencies` section
of `package.json`, but this meant that its own dependencies are treated as
dependencies of the main project: Babel, for example.
Generally, $localize` is not used at runtime - it is compiled out by the
translation tooling, so there is no need for it to be a full dependency.
In fact, even if it is used at runtime, the package itself is only used
at dev-time since the runtime bits will be bundled into a distributable.
So putting this package in `devDependencies` would only prevent libraries
from bringing the package into application projects that used them. This
is probably good in itself, since it should be up to the downstream project
to decide if it wants to include `@angular/localize` at runtime.
This commit changes the default location of the package to be the
`devDependencies` section, but gives an option `useAtRuntime` to choose
otherwise.

Previously, the `sourceSpan` and `startSourceSpan` were the same
object, which meant that you had the following situation:
```
element = <div>some content</div>
sourceSpan = <div>
startSourceSpan = <div>
endSourceSpan = </div>
```
This made `sourceSpan` redundant and meant that if you
wanted a span for the whole element including its content
and closing tag, it had to be computed.
Now `sourceSpan` is separated from `startSourceSpan`
resulting in:
```
element = <div>some content</div>
sourceSpan = <div>some content</div>
startSourceSpan = <div>
endSourceSpan = </div>
```

Previously, the `startSourceSpan` property could be null
but in reality it is always well defined - except for a legacy
case in the old i18n extraction/merging code, where the
typings for source-spans are already being undermined.
Making this property non-null, simplifies code elsewhere
in the project.

Previously the lexer was responsible for deciding whether an "inline"
template should also have its line-endings normalized.
Now this decision is made higher up in the call stack to allow more
flexibility in the parser/lexer.

This commit ensures that the `updateValueAndValidity` method takes the
`asyncValidator` into consideration to emit on the `statusChanges` observables.
This is necessary so that any subsequent changes are emitted properly to any
subscribers.
Closes#20424Closes#14542
BREAKING CHANGE:
Previously if FormControl, FormGroup and FormArray class instances had async validators
defined at initialization time, the status change event was not emitted once async validator
completed. After this change the status event is emitted into the `statusChanges` observable.
If your code relies on the old behavior, you can filter/ignore this additional status change
event.

The HTML parser gets an element's namespace either from the tag name
(e.g. `<svg:rect>`) or from its parent element `<svg><rect></svg>`) which
breaks down when an element is inside of an SVG `foreignElement`,
because foreign elements allow nodes from a different namespace to be
inserted into an SVG.
These changes add another flag to the tag definitions which tells child
nodes whether to try to inherit their namespaces from their parents.
It also adds a definition for `foreignObject` with the new flag,
allowing elements placed inside it to infer their namespaces instead.

In several occasions it has been observed when the browser has evicted
eagerly cached assets from the cache and which can also not be found on the
server anymore. This can lead to broken state where only parts of the application
will load and others will fail.
This commit fixes this issue by checking for the missing asset in the cache
and on the server. If this condition is true, the broken client will be
notified about the current state through the `UnrecoverableStateError`.

Currently the merge script default branch configuration throws an error
if an unexpected version branch is discovered. The error right now
assumes to much knowledge of the logic and the document outlining
the release trains conceptually.
We change it to something more easy to understand that doesn't require
full understanding of the versioning/labeling/branching document that
has been created for the Angular organization.

Update the API used to request a timestamp. The previous API we relied on for this
test application, worldclockapi.com no longer serves times and simply 403s on all
requests. This caused our test to timeout as the HTTP request did not handle a failure
case. By moving to a new api, the HTTP request responds as expected and timeouts
are corrected as there is not longer a pending microtask in the queue.

Prior to this commit, a lot of internal-only class properties and methods (such as `ngOnChanges`)
of the Forms package directives were exposed on angular.io website. These fields are not expected
to be called externally (they are used/invoked by framework only), since they are part of internal
implementations of the following interfaces:
* Angular lifecycle hook interfaces
* ControlValueAccessor interface
* Validator interface
Having these internal-only fields in docs creates unnecessary noise on directive detail pages.
This commit adds the `@nodoc` annotation to these properties and methods to keep fields in the
golden files, but hide them in docs.
