When building a library, the `rootDir` option is configured to ensure
that all source files are present within the entry-point that is being
build. This imposes an extra constraint on the reference emit logic,
which does not allow emitting a reference into a source file outside of
this `rootDir`.
During the generation of type-check blocks we used to make a best-effort
estimation of whether a type reference can be emitted into the
type-check file. This check was relaxed in #42492 to support emitting
more syntax forms and type references, but this change did not consider
the `rootDir` constraint that is present in library builds. As such, the
compiler might conclude that a type reference is eligible for emit into
the type-check file, whereas in practice this would cause a failure.
This commit changes the best-effort estimation into a "preflight"
reference emit that is fully accurate as to whether emitting a type
reference is possible.

The `NgtscCompilerHost` is implemented using the `FileSystem`
abstraction of the compiler, which is implemented for tests using an
in-memory `MockFileSystem`. If the in-memory filesystem contains
symlinks, then using `NgtscCompilerHost` would not reflect their
resolved real path. Instead, the TypeScript compiler would use its
default implementation based on the real filesystem, which is unaware of
the in-memory `MockFileSystem` setup.
This change does not currently address any issues, but is being fixed
as it prevented a reproduction scenario from behaving correctly.

In certain scenarios, the compiler may have crashed with an
`Unable to write a reference` error which would be particularly hard
to diagnose. One of the primary reasons for this failure is when the
`rootDir` option is configured---typically the case for libraries---
and a source file is imported using a relative import from an external
entry-point. This would normally report TS6059 for the invalid relative
import, but the crash prevents this error from being surfaced.
This commit refactors the reference emit logic to result in an explicit
`Failure` state with a reason as to why the failure occurred. This state
is then used to report a `FatalDiagnosticException`, preventing a hard
crash.

Improve docs "Understanding Angular-Directives-Attribute Directives"
In `highlight.directive.1.ts`, add the `private` keyword for `el` property
to make it correct and consistent with subsequent examples.
For section "Setting the value with user input", add a step to tell the
reader change the method `onMouseEnter`, thus more readable.
For section "Binding to a second property", delete the aliase for the
`Input` property, and changes the name back to `appHighlight` in the code
to make it consistent with the whole tutorial.

Fixes a couple of tests that have been flaking our test runs. The two tests actually failed consistently when run in isolation, but they passed if at least one test ran before them. My understanding was that they failed, because they were running outside of the `NgZone` which meant that the errors being thrown inside of a `Promise` weren't being flushed.

Temporarily disables the components repo unit tests job that
breaks due to us changing the devmode output to ES2015 in Angular Bazel.
This is a trivial thing to solve in the COMP repo but the job needs

* `forwardRef` does not work with ES2015 and TypeScript's decorator

Updates the acceptance core tests to work with ES2015 devmode output.
There were two issues surfacing:
* The NodeJS test execution failed because Domino does not handle
destructuring syntax properly. This is because `Node.children` is not
an iterable.
* `forwardRef` does not work with ES2015 and TypeScript's decorator
downlevel emit. This is a known limitation we work around in Angular
applications by either compiling tests with the Angular compiler, or
by running a custom decorator downlevel transform (like in the CLI).

To make our test output i.e. devmode output more aligned
with what we produce in the NPM packages, or to be more
aligned with what Angular applications will usually consume,
the devmode output is switched from ES5 to ES2015.
Additionally various tsconfigs (outside of Bazel) have been
updated to match with the other parts of the build. The rules
are:
ES2015 for test configurations, ES2020 for actual code that will
end up being shipped (this includes the IDE-only tsconfigs).

This commit refactors the code of the base validators class to make it compatible with the property renaming optimization.
