Angular 16 (#2007)

* Removed adv, which isn't needed.

* Updated zone

* Updated to angular 16

* Updated to angular 16 (partially)

* Updated to angular 16

* Package update for Angular 16 (and other dependencies) is complete.

* Replaced all takeUntil(this.onDestroy) with new takeUntilDestroyed()

* Updated all inputs that have ! to be required and deleted all unit tests.

* Corrected how takeUntilDestroyed() is supposed to be implemented.
