feat(core): introduce TestBed.tick() (#60993)

This commit introduces the `TestBed.tick()` method that, similarly to the `ApplicationRef.tick()`, synchronizes state with the DOM. It can be used in unit tests to mimic framework's logic executed in production applications. The `TestBed.tick()` should be used instead of the removed `TestBed.flushEffects()`. BREAKING CHANGE: the `TestBed.flushEffects()` was removed - use the `TestBed.tick()` instead. PR Close #60993
