In ES5 and ES2015, class identifiers may have aliases. Previously, the
`NgccReflectionHost`s recognized the following formats:
- ES5:
```js
var MyClass = (function () {
function InnerClass() {}
InnerClass_1 = InnerClass;
...
}());
```
- ES2015:
```js
let MyClass = MyClass_1 = class MyClass { ... };
```
In addition to the above, this commit adds support for recognizing an
alias outside the IIFE in ES5 classes (which was previously not
supported):
```js
var MyClass = MyClass_1 = (function () { ... }());
```

`Esm5ReflectionHost#getInnerFunctionDeclarationFromClassDeclaration()`
was already called with `ts.Declaration`, not `ts.Node`, so we can
tighten its parameter type and get rid of a redundant check.
`getIifeBody()` (called inside
`getInnerFunctionDeclarationFromClassDeclaration()`) will check whether
the given `ts.Declaration` is a `ts.VariableDeclaration`.

Prior to this commit, decorator handling logic in Ngtsc used `Error` to throw errors. This commit replaces most of these instances with `FatalDiagnosticError` class, which provider a better diagnostics error (including location of the problematic code).

We recently updated chokidar to `3.0.0`. The latest version of
chokidar provides TypeScript types on its own and makes the extra
dependency on the `@types` unnecessary.
This seems to have caused the `build-packages-dist` script to fail with
an error like:
```
[strictDeps] transitive dependency on external/npm/node_modules/chokidar/types/index.d.ts
not allowed. Please add the BUILD target to your rule's deps.
```
It's unclear why that happens, but a reasonable theory would be that
the TS compilation accidentally picked up the types from `chokidar`
instead of `@types/chokidar`, and the strict deps `@bazel/typescript`
check reported this as issue because it's not an explicit target dependency.

ngcc uses a lockfile to prevent two ngcc instances from executing at the
same time. Previously, if a lockfile was found the current process would
error and exit.
Now, when in async mode, the current process is able to wait for the previous
process to release the lockfile before continuing itself.

In Ivy's template type checker, event bindings are checked in a closure
to allow for accurate type inference of the `$event` parameter. Because
of the closure, any narrowing effects of template guards will no longer
be in effect when checking the event binding, as TypeScript assumes that
the guard outside of the closure may no longer be true once the closure
is invoked. For more information on TypeScript's Control Flow Analysis,
please refer to https://github.com/microsoft/TypeScript/issues/9998.
In Angular templates, it is known that an event binding can only be
executed when the view it occurs in is currently rendered, hence the
corresponding template guard is known to hold during the invocation of
an event handler closure. As such, it is desirable that any narrowing
effects from template guards are still in effect within the event
handler closure.
This commit tweaks the generated Type-Check Block (TCB) to repeat all
template guards within an event handler closure. This achieves the
narrowing effect of the guards even within the closure.

The `TargetedEntryPointFinder` must work out what the
containing package is for each entry-point that it finds.
The logic for doing this was flawed in the case that the
package was in a path-mapped directory and not in a
node_modules folder. This meant that secondary entry-points
were incorrectly setting their own path as the package
path, rather than the primary entry-point path.

This commit implements an experimental integration with tsc_wrapped, where
it can load the Angular compiler as a plugin and perform Angular
transpilation at a user's request.
This is an alternative to the current ngc_wrapped mechanism, which is a fork
of tsc_wrapped from several years ago. tsc_wrapped has improved
significantly since then, and this feature will allow Angular to benefit
from those improvements.
Currently the plugin API between tsc_wrapped and the Angular compiler is a
work in progress, so NgTscPlugin does not yet implement any interfaces from
@bazel/typescript (the home of tsc_wrapped). Instead, an interface is
defined locally to guide this standardization.

This commit moves the calculation of `ignoreFiles` - the set of files to be
ignored by a consumer of the `NgCompiler` API - from its `prepareEmit`
operation to its initialization. It's now available as a field on
`NgCompiler`.
This will allow a consumer to skip gathering diagnostics for `ignoreFiles`
as well as skip emit.

A bug previously caused the template type-checking diagnostics produced by
TypeScript for template expressions to use -99-prefixed error codes. These
codes are converted to "NG" errors instead of "TS" errors during diagnostic
printing. This commit fixes the issue.
PR Close#35146
In #34021 the ngtsc compiler gained the ability to emit type parameter
constraints, which would generate imports for any type reference that
is used within the constraint. However, the `AbsoluteModuleStrategy`
reference emitter strategy did not consider interface declarations as a
valid declaration it can generate an import for, throwing an error
instead.
This commit fixes the issue by including interface declarations in the
logic that determines whether something is a declaration.

In #33551, a bug in `ngc --watch` mode was fixed so that a component is
recompiled when its template file is changed. Due to insufficient
normalization of files paths, this fix did not have the desired effect

To support parallel CLI builds we instruct developers to pre-process
their node_modules via ngcc at the command line.
Despite doing this ngcc was still trying to set a lock when it was being
triggered by the CLI for packages that are not going to be processed,
since they are not compiled by Angular for instance.
This commit checks whether a target package needs to be compiled
at all before attempting to set the lock.

If ngcc gets updated to a new version then the artifacts
left in packages that were processed by the previous
version are possibly invalid.
Previously we just errored if we found packages that
had already been processed by an outdated version.
Now we automatically clean the packages that have
outdated artifacts so that they can be reprocessed
correctly with the current ngcc version.

Now `hasBeenProcessed()` will no longer throw if there
is an entry-point that has been built with an outdated
version of ngcc.
Instead it just returns `false`, which will include it in this
processing run.
This is a precursor to adding functionality that will
automatically revert outdate build artifacts.
