Previously, clients were notified about updates sequentially. This
wasn't necessary.
This commit changes the `Driver#notifyClientsAboutUpdate()` method to
notify the clients in parallel (by switching from `Array#reduce()` to
`Array#map()` and `Promise.all()`).
This also aligns the `notifyClientsAboutUpdate()` method with the
`notifyClientsAboutUnrecoverableState()` method.

Previously, the `Driver#notifyClientsAboutUnrecoverableState()` method
would not wait for the completion of the promises created to notify the
clients. Theoretically, this could result in the SW instance's getting
destroyed by the browser before all clients have been notified. This is
extremely unlikely to happen in practice, since the async operations are
very quick, but it _is_ theoretically possible.
This commit ensures that the SW instance will remain alive while
notifying the clients by making `notifyClientsAboutUnrecoverableState()`
await the notification promises.

The decorator downleveling transform patches `ts.EmitResolver.isReferencedAliasDeclaration`
to prevent elision of value imports that occur only in a type-position, which would
inadvertently install the patch repeatedly for each source file in the program.
This could potentially result in a stack overflow when a very large number of files is
present in the program.
This commit fixes the issue by ensuring that the patch is only applied once.
This is also a slight performance improvement, as `isReferencedAliasDeclaration`
is no longer repeatedly calling into all prior installed patch functions.

Previously, if there were path-mapped entry-points, where one contaied the
string of another - for example `worker-client` and `worker` - then the
base paths were incorrectly computed resulting in the wrong package path
for the longer entry-point. This was because, when searching for a matching
base path, the strings were tested using `startsWith()`, whereas we should
only match if the path was contained in a directory from a file-system
point of view.
Now we not only check whether the target path "starts with" the base path
but then also whether the target path is actually contained in the base path
using `fs.relative()`.

When we attach a `ViewRef` to a `ViewContainerRef`, we save a reference to the container
onto the `ViewRef` so that we can remove it when the ref is destroyed. The problem is
that if the container's `hostView` is destroyed first, the `ViewRef` has no way of knowing
that it should stop referencing the container.
These changes remove the leak by not saving a reference at all. Instead, when a `ViewRef`
is destroyed, we clean it up through the `LContainer` directly. We don't need to worry
about the case where the container is destroyed before the view, because containers
automatically clean up all of their views upon destruction.

The `NgControlStatusGroup` directive is shared between template-driven and reactive form modules. In cases when
only reactive forms module is present, the `NgControlStatusGroup` directive is still activated on all `<form>`
elements, but if there is no other reactive directive applied (such as `formGroup`), corresponding `ControlContainer`
token is missing, thus causing exceptions (since `NgControlStatusGroup` directive relies on it to determine the
status). This commit updates the logic to handle the case when no `ControlContainer` is present (effectively making
directive logic a noop in this case).
Alternative approach (more risky) worth considering in the future is to split the `NgControlStatusGroup` into
2 directives with different set of selectors and include them into template-driven and reactive modules separately.
The downside is that these directives might be activated simultaneously on the same element (e.g. `<form>`),
effectively doing the work twice.

This commit fixes the Template Type Checker's `getSymbolOfNode` so that
it is able to retrieve a symbol for the `BoundEvent` of a two-way

for the input because it appeared first and shares the same `keySpan` as
the event binding. To fix this, the TCB node search now verifies that
the located node matches the expected name for the output subscription:
either `addEventListener` for a native listener or the class member of the Angular `@Output`
in the case of an Angular output, as would be the case for two-way
bindings.

Currently when analyzing the metadata of a directive, we bundle together the bindings from `host`
and the `HostBinding` and `HostListener` together. This can become a problem later on in the
compilation pipeline, because we try to evaluate the value of the binding, causing something like
`@HostBinding('class.foo') public true = 1;` to be treated the same as
`host: {'[class.foo]': 'true'}`.
While looking into the issue, I noticed another one that is closely related: we weren't treating
quoted property names correctly. E.g. `@HostBinding('class.foo') public "foo-bar" = 1;` was being
interpreted as `classProp('foo', ctx.foo - ctx.bar)` due to the same issue where property names
were being evaluated.
These changes resolve both of the issues by treating all `HostBinding` instance as if they're
reading the property from `this`. E.g. the `@HostBinding('class.foo') public true = 1;` from above
is now being treated as `host: {'[class.foo]': 'this.true'}` which further down the pipeline becomes
`classProp('foo', ctx.true)`. This doesn't have any payload size implications for existing code,
because we've always been prefixing implicit property reads with `ctx.`. If the property doesn't
have an identifier that can be read using dotted access, we convert it to a quoted one (e.g.
`classProp('foo', ctx['is-foo']))`.

`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.
