refactor(testing): introduce new testing api to support ng modules

BREAKING CHANGE:
- deprecations:
  * `withProviders`, use `TestBed.withModule` instead
  * `addProviders`, use `TestBed.configureTestingModule` instead
  * `TestComponentBuilder`, use `TestBed.configureTestModule` / `TestBed.override...` / `TestBed.createComponent` instead.

Closes #10354
