In `ViewEncapsulation.Emulated` mode the compiler converts `:host` and
`:host-context` pseudo classes into new CSS selectors.
Previously, when there was both `:host-context` and `:host` classes in a
selector, the compiler was generating incorrect selectors. There are two
scenarios:
* Both classes are on the same element (i.e. not separated). E.g.
`:host-context(.foo):host(.bar)`. This setup should only match the
host element if it has both `foo` and `bar` classes. So the generated
CSS selector should be: `.foo.bar<hostmarker>`.
* The `:host` class is on a descendant of the `:host-context`. E.g.
`:host-context(.foo) :host(.bar)`. This setup should only match the
`.foo` selector if it is a proper ancestor of the host (and not on the
host itself). So the generated CSS selector should be:
`.foo .bar<hostmarker>`.
This commit fixes the generation to handle these scenarios.

In `ViewEncapsulation.Emulated` mode, the compiler must generate additional
combinations of selectors to handle the `:host-context()` pseudo-class function.
Previously, when there is was more than one `:host-context()` selector in a
rule, the compiler was generating invalid selectors.
This commit generates all possible combinations of selectors needed to
match the same elements as the native `:host-context()` selector.

In Chrome 83 passing a TrustedScript to eval just returns the
TrustedScript back without evaluating it, causing the
newTrustedFunctionFor{Dev,JIT} functions to fail. This is a browser bug
that has been fixed in Chrome 84, and only affects Angular applications
running with JIT (which includes unit tests).
As a temporary workaround for users still on Chrome 83, detect when this
occurs in the newTrustedFunctionFor* functions and fall back to the
straightforward, non-Trusted Types compatible implementation. The only
combination that is left affected consists of Angular applications
running with JIT, that have explicitly configured Trusted Types in
enforcement mode, with users that are still on Chrome 83.
Also correct docstring for newTrustedFunctionForJIT.

`@angular/platform-server` provides the foundation for rendering an
Angular app on the server. In order to achieve that, it uses a
server-side DOM implementation (currently [domino][1]).
For rendering on the server to work as closely as possible to running
the app on the browser, we need to make DOM globals (such as `Element`,
`HTMLElement`, etc.), which are normally provided by the browser,
available as globals on the server as well.
Currently, `@angular/platform-server` achieves this by extending the
`global` object with the DOM implementation provided by `domino`. This
assignment happens in the [setDomTypes()][2] function, which is
[called in a `PLATFORM_INITIALIZER`][3]. While this works in most cases,
there are some scenarios where the DOM globals are needed sooner (i.e.
before initializing the platform). See, for example, #24551 and #39950
for more details on such issues.
This commit provides a way to solve this problem by exposing a
side-effect-ful entry-point (`@angular/platform-server/init`), that
shims the `global` object with DOM globals. People will be able to
import this entry-point in their server-rendered apps before
bootstrapping the app (for example, in their `main.server.ts` file).
(See also [#39950 (comment)][4].)
In a future update, the [`universal` schematics][5] will include such an
import by default in newly generated projects.

This commit causes imports added by ngtsc's `ImportManager` to have their
TypeScript "original node" set to the generated `ts.ImportDeclaration`
statement.
In g3, the tsickle transformer runs after the Angular transformer and post-
processes Angular's compilation output. One of its post-processing tasks is
to transform generated imports and references to imported symbols from the
commonjs module system to the g3 module system. Part of this transformation
involves recognizing modules with specific metadata and altering references
to symbols from those modules accordingly.
Normally, tsickle can rely on TypeScript's binding for an imported symbol to
find its origin module and thus the correct metadata for the symbol. However
the Angular transform generates new synthetic imports which don't have such
binding information. Angular's imports are always namespace imports of the
form:
```
import * as qualifier 'module/specifier';
```
References to such an import are then of the form `qualifier.SymbolName`.
To process such imports properly, tsickle needs to be able to associate the
reference to `qualifier` in the expression `qualifer.SymbolName` with the
`ts.ImportDeclaration` statement that defines it. It expects to do this by
looking at the `ts.getOriginalNode()` for the `qualifier` reference, which
should be the `ts.ImportDeclaration`. This commit changes ngtsc's import
generation mechanism to set the original node on `qualifier` identifiers
according to this expectation.
This commit is not tested in the direct compiler tests, since:
1) there is no observable behavior externally from setting the original node
2) we don't have tests that intercept transformer operations (which could be
used to directly assert against the AST nodes)
3) tsickle's published version does not (yet) contain the g3-specific
transformations which rely on the original node and would thus allow the
behavior to be observed.
Instead, we rely on the g3 testing suite to validate the correctness of this
fix. Breaking this functionality would cause g3 compilation errors for
targets, since tsickle would be unable to transform imports correctly.

The parser does not include parenthesis in the AST, so if a LHS
expression would be parenthesized then its start span would start
after the opening parenthesis. Previously, some parent AST nodes would
be created with the start span of its LHS as its own start, so this
resulted in the parent AST node not encompassing the opening parenthesis
in its source span. This commit fixes the issue by capturing the start
index prior to parsing a child AST tree, which is then used as the
start of the source span of the the parent AST node that is parsed.

When using the [timeout attribute](https://xhr.spec.whatwg.org/#the-timeout-attribute) and an XHR
request times out, browsers trigger the `timeout` event (and execute the XHR's `ontimeout`

has been explicitly set on the XHR.
In the above cases, `HttpClient` would fail to capture the XHR's completing (with an error), so
the corresponding `Observable` would never complete.

When the downleveling helper function has been inlined into the
`$localize` call, it is a bit more tricky to parse out the cooked and
raw strings. There was already code to do this but it assumed that
the `cooked` and `raw` items were both arrays.
Sometimes the `raw` array is just a copy of the `cooked` array
via an expression similar to `raw || (raw=tcookedslice(0))`. This
commit changes the `unwrapMessagePartsFromLocalizeCall()`
function to be able to handle such a situation.

Currently zone.js patches `setTimeout` and keeps a `tasksByHandleId` map to keep `timerId` <-> `ZoneTask`
relationship. This is needed so that when `clearTimeout(timerId)` is called, zone.js can find the associated
`ZoneTask`. Now zone.js set the `tasksByHandleId` map in the `scheduleTask` function, but if the `setTimeout`
is running in the `FakeAsyncZoneSpec` or any other `ZoneSpec` with `onScheduleTask` hooks. The `scheduleTask`
in `timer` patch may not be invoked.
For example:
```
fakeAsync(() => {
setTimeout(() => {});
tick();
});
```
In this case, the `timerId` kept in the `tasksByHandleId` map is not cleared.
This is because the `FakeAsyncZoneSpec` in the `onScheduleTask` hook looks like this.
```
onScheduleTask(delegate, ..., task) {
fakeAsyncScheduler.setTimeout(task);
return task;
}
```
Because `FakeAsyncZoneSpec` handles the task itself and it doesn't call `parentDelegate.onScheduleTask`,
therefore the default `scheduleTask` in the `timer` patch is not invoked.
In this commit, the cleanup logic is moved from `scheduleTask` to `setTimeout` patch entry to
avoid the memory leak.

Two motivations behind this change:
1. We would like to expose the types of the Language Service to external
users (like the VSCode extension) via the npm package, on the top
level of the package
2. We would like the View Engine and Ivy LS to share a common interface
(notably after the inclusion of `getTcb`, the Ivy LS upholds a
strict superset of `ts.LanguageService`; previously both VE and Ivy
LS were aligned on `ts.LanguageService`.)
To this end, this commit refactors the exports on the toplevel of the
`language-service/` package to just be types common to both the VE and
Ivy language services. The VE and Ivy build targets then import and use
these types accordingly, and the expectation is that an external user
will just import the relevant typings from the toplevel package without
diving into either the VE or Ivy sources.
