Chuck Jazdzewski dd8679037e fix(compiler-cli): do not fold errors past calls in the collector (#21708)
Folding errors passed calls prevented the static reflector from
begin able to ignore errors in annotations it doesn't know as
the call to the unknown annotation was elided from the metadata.

Chuck Jazdzewski e7d9cb3e4c feat(compiler): narrow types of expressions used in *ngIf (#20702)
Structural directives can now specify a type guard that describes
what types can be inferred for an input expression inside the
directive's template.

NgIf was modified to declare an input guard on ngIf.

After this change, `fullTemplateTypeCheck` will infer that
usage of `ngIf` expression inside it's template is truthy.

For example, if a component has a property `person?: Person`
and a template of `<div *ngIf="person"> {{person.name}} </div>`
the compiler will no longer report that `person` might be null or
undefined.

The template compiler will generate code similar to,

```
  if (NgIf.ngIfTypeGuard(instance.person)) {
    instance.person.name
  }
```

to validate the template's use of the interpolation expression.
Calling the type guard in this fashion allows TypeScript to infer
that `person` is non-null.

Fixes: #19756?

Chuck Jazdzewski 8ecda94899 feat(compiler-cli): improve error messages produced during structural errors (#20459)
The errors produced when error were encountered while interpreting the
content of a directive was often incomprehencible. With this change
these kind of error messages should be easier to understand and diagnose.

Chuck Jazdzewski a75040d0a1 refactor(compiler): bump metadata version to 4 (#19338)
Also adds auto upgrade from lower version based
on the .d.ts file (e.g. from version 3 to 4).

This is needed as we are now also capturing type aliases
in metadata files (and we rely on this),
see 6e3498ca8e.

Tobias Bosch 62602b9bd8 fix(compiler): collect non exported symbols in d.ts files (#19301)

Matias Niemelä 4695c69cf1 refactor(compiler): remove all source-level traces to tsc-wrapped (#18966)
- temporarily keeps the old sources under packages/tsc-wrapped
  until the build scripts are changed to use compiler-cli everywhere.
- removes the compiler options `disableTransformerPipeline` that was introduced
  in a previous beta of Angular 5, i.e. the transformer based compiler
  is now always enabled.
