feat(compiler): reuse the TypeScript typecheck for template typechecking. (#19152)

This speeds up the compilation process significantly.

Also introduces a new option `fullTemplateTypeCheck` to do more checks in templates:
- check expressions inside of templatized content (e.g. inside of `<div *ngIf>`).
- check the arguments of calls to the `transform` function of pipes
- check references to directives that were exposed as variables via `exportAs`
