Now that the Angular LS is a proper tsserver plugin, it does not make
sense for it to maintain its own language service API.
This is part one of the effort to remove our custom LanguageService
interface.
This interface is cumbersome because we have to do two transformations:
ng def -> ts def -> lsp definition
The TS LS interface is more comprehensive, so this allows the Angular LS
to return more information.
PR Close#31972
This PR changes the language service to work in two different modes:
1. TS + Angular
Plugin augments TS language service to provide additonal Angular
information. This only works with inline template and is meant to be
used as a local plugin (configured via tsconfig.json).
2. Angular only
Plugin only provides information on Angular templates, no TS info at
all. This effectively disables native TS features and is meant for
internal use only.
Default mode is `angularOnly = false` so that we don't break any users
already using Angular LS as local plugin.
As part of the refactoring, `undefined` is removed from type aliases
because it is considered bad practice.
go/tsstyle#nullableundefined-type-aliases
```
Type aliases must not include |null or |undefined in a union type.
Nullable aliases typically indicate that null values are being passed
around through too many layers of an application, and this clouds the
source of the original issue that resulted in null. They also make it
unclear when specific values on a class or interface might be absent.

Fixes all TypeScript failures caused by enabling the `--strict`
flag for test source files. We also want to enable the strict
options for tests as the strictness enforcement improves the
overall codehealth, unveiled common issues and additionally it
allows us to enable `strict` in the `tsconfig.json` that is picked
up by IDE's.

```
NgLSHost: AngularLanguageServiceHost
NgLS: AngularLanguageService
```
NgLSHost should not depend on NgLS, because it introduces circular
dependency.
Instead, the `getTemplateAst` and `getTemplatAstAtPosition` methods should
be moved to NgLSHost and exposed as public methods.
This removes the circular dependency, and also removes the need for the
awkward 'setSite' method in NgLSHost.

With this change we reduce the amount of IO operations. This is especially a huge factor in windows since IO ops are slower.
With this change mainly we cache `existsSync` and `readFileSync` calls

Since we recently removed the `test.sh` script, and now run all
tests with Bazel, we can remove the unused logic that makes language-service
tests pass in non-Bazel.
This cleans up the tests, and also makes it easier to write tests
without worrying about two ways of the Angular package output
(Bazel `ng_package` rules vs. old `build.sh` logic of building)

Typescript 3.2 introduced BigInt type, and consequently the
implementation for checkExpressionWorker() in checkers.ts is refactored.
For NumberLiteral and StringLiteral types, 'text' filed must be present
in the Node type, therefore they must be LiteralLikeNode instead of
Node.

We are close enough to blacklist a few test targets, rather than whitelist targets to run...
Because bazel rules can be composed of other rules that don't inherit tags automatically,
I had to explicitly mark all of our ts_library and ng_module targes with "ivy-local" and
"ivy-jit" tags so that we can create a query that excludes all fixme- tagged targets even
if those targets are composed of other targets that don't inherit this tag.
This is the updated overview of ivy related bazel tags:
- ivy-only: target that builds or runs only under ivy
- fixme-ivy-jit: target that doesn't yet build or run under ivy with --compile=jit
- fixme-ivy-local: target that doesn't yet build or run under ivy with --compile=local
- no-ivy-jit: target that is not intended to build or run under ivy with --compile=jit
- no-ivy-local: target that is not intended to build or run under ivy with --compile=local

All errors for existing fields have been detected and suppressed with a

Issue/24571 is tracking proper clean up of those instances.
One-line change required in ivy/compilation.ts, because it appears that
the new syntax causes tsickle emitted node to no longer track their
original sourceFiles.
