During route activation, a componentless route will not have a context created
for it, but the logic continues to recurse so that children are still
activated. This can be seen here:
362f45c4bf/packages/router/src/operators/activate_routes.ts (L151-L158)
The current deactivation logic does not currently account for componentless routes.
This commit adjusts the deactivation logic so that if a context cannot
be retrieved for a given route (because it is componentless), we
continue to recurse and deactivate the children using the same
`parentContexts` in the same way that activation does.

We need a means to preserve typecheck files when a project is reloaded,
otherwise the Ivy compiler will throw an error when it's unable to find
them. This commit implements `getExternalFiles()` called by the langauge
server to achieve this goal.

`ts.server.ServerHost.resolvePath()` is different from Angular's
`FileSystem.resolve()` because the signature of the former is
```ts
resolvePath(path: string): string; // ts.server.ServerHost
```
whereas the signature of the latter is
```ts
resolve(...paths: string[]): AbsoluteFsPath; // FileSystem on compiler-cli
```
The current implementation calls `path.join()` to concatenate all the input
paths and pass the result to `ts.server.ServerHost.resolvePath()`, but doing
so results in filenames like
```
/foo/bar/baz/foo/bar/baz/tsconfig.json
```
if both input paths are absolute.
`ts.server.ServerHost` should not be used to implement the
`resolve()` method expected by Angular's `FileSystem`.
We should use Node's `path.resolve()` instead, which will correctly collapse
the absolute paths.

When resolving references, the Ivy compiler has a few strategies it could use.
For relative path, one of strategies is [`RelativePathStrategy`](
https://github.com/angular/angular/blob/master/packages/compiler-cli/src/
ngtsc/imports/README.md#relativepathstrategy). This strategy
relies on `compilerOptions.rootDir` and `compilerOptions.rootDirs` to perform
the resolution, but language service only passes `rootDirs` to the compiler,
and not `rootDir`.
In reality, `rootDir` is very different from `rootDirs` even though they
sound the same.
According to the official [TS documentation][1],
> `rootDir` specifies the root directory of input files. Only use to control
> the output directory structure with --outDir.
> `rootDirs` is a list of root folders whose combined content represent the
> structure of the project at runtime. See [Module Resolution documentation](
> https://www.typescriptlang.org/docs/handbook/
> module-resolution.html#virtual-directories-with-rootdirs)
> for more details.
For now, we keep the behavior between compiler and language service consistent,
but we will revisit the notion of `rootDir` and how it is used later.

CSS supports escaping in selectors, e.g. writing `.foo:bar` will match an element with the
`foo` class and `bar` pseudo-class, but `.foo\:bar` will match the `foo:bar` class. Our
shimmed shadow DOM encapsulation always assumes that `:` means a pseudo selector
which breaks a selector like `.foo\:bar`.
These changes add some extra logic so that escaped characters in selectors are preserved.

In some browsers, notably a mobile version of webkit on iPad, the

Currently we check whether a property binding contains an interpolation using a regex so
that we can throw an error. The problem is that the regex doesn't account for quotes
which means that something like `[prop]="'{{ foo }}'"` will be considered an error, even
though it's not actually an interpolation.
These changes build on top of the logic from #39826 to account for interpolation
characters inside quotes.

The trustConstantHtml and trustConstantResourceUrl functions are only
meant to be passed constant strings extracted from Angular application
templates, as passing other strings or variables could introduce XSS
vulnerabilities.
To better protect these APIs, turn them into template tags. This makes
it possible to assert that the associated template literals do not
contain any interpolation, and thus must be constant.
Also add tests for the change to prevent regression.

When talking about parameter inheritance, one might think that matrix
parameters can be inherited from the "parent" segment, or the segment
which appears immediately to the left. In reality, when we talk about
a "parent" in the `Router`, we mean the parent `Route` config. This
config may contain more than one segment and matrix parameters must
appear at the end or they do not "belong" to any config.

There are two parts to this commit:
1. Revert the changes from #38379. This change had an incomplete view of
how things worked and also diverged the implementations of
`applyRedirects` and `recognize` even more.
2. Apply the fixes from the `recognize` algorithm to ensure that named
outlets with empty path parents can be matched. This change also passes
all the tests that were added in #38379 with the added benefit of being
a more complete fix that stays in-line with the `recognize` algorithm.
This was made possible by using the same approach for `split` by
always creating segments for empty path matches (previously, this was
only done in `applyRedirects` if there was a `redirectTo` value). At the
end of the expansions, we need to squash all empty segments so that
serializing the final `UrlTree` returns the same result as before.

The `applyRedirects` and `recognize` algorithms have the same overall goal:
match a `UrlTree` with the application's `Routes` config. There are a
few key functions in these algorithms which can be shared rather than
duplicated between the two. This also makes it easier to see how the two
are similar and where they diverge.
PR Close#40029
This commit updates the `recognize` algorithm to work with named outlets
which have empty path parents. For example, given the following config
```
const routes = [
{
path: '',
children: [
{path: 'a', outlet: 'aux', component: AuxComponent}
]}
];
```
The url `/(aux:a)` should match this config. In order to do so, we need
to allow the children of `UrlSegmentGroup`s to match a `Route` config
for a different outlet (in this example, the `primary`) when it's an
empty path. This should also *only* happen if we were unable to find a
match for the outlet in the level above. That is, the matching strategy
is to find the first `Route` in the list which _matches the given
outlet_. If we are unable to do that, then we allow empty paths from
other outlets to match and try to find some child there whose outlet
matches our segment.

To make the tests suite easier to follow, `Recognize#apply` can be made

This commit updates the `recognize` algorithm to return `null` when a
segment does not match a given config rather than throwing an error.
This makes the code much easier to follow because the "no match" result
has to be explicitly handled rather than catching the error in very
specific places.

When stepping through the `recognize` algorithm, it is much easier to
follow when using a simple `for...of` rather than the helper
`mapChildrenIntoArray` with the passed closure. The only special thing that
`mapChildrenIntoArray` does is ensure the primary route appears first.
This change will have no affect on the result because `processChildren` later calls
`sortActivatedRouteSnapshots`, which does the same thing.

Prior to this commit, removing `FormControlDirective` and `FormGroupName` directive instances didn't clear
the callbacks previously registered on FromControl/FormGroup class instances. As a result, these callbacks
were executed even after `FormControlDirective` and `FormGroupName` directive instances were destroyed. That was
also causing memory leaks since these callbacks also retained references to DOM elements.
This commit updates the cleanup logic to take care of properly detaching FormControl/FormGroup/FormArray instances
from the view by removing view-specific callback at destroy time.

DI providers can be defined via `useFactory` function, which may have arguments configured via `deps` array.
The `deps` array may contain DI flags represented by DI decorators (such as `@Self`, `@SkipSelf`, etc). Prior to this
commit, having the `@Host` decorator in `deps` array resulted in runtime error in Ivy. The problem was that the `@Host`

This commit updates the logic which prepares `useFactory` arguments to recognize the `@Host` decorator.

Given the template
`<div (click)="doSomething($event)"></div>`
If you request references for the `$event`, the results include both `$event` and `(click)="doSomething($event)"`.
This happens because in the TCB, `$event` is passed to the `subscribe`/`addEventListener`
function as an argument. So when we ask typescript to give us the references, we
get the result from the usage in the subscribe body as well as the one passed in as an argument.
This commit adds an identifier to the `$event` parameter in the TCB so
that the result returned from `getReferencesAtPosition` can be
identified and filtered out.
