Alex Rickabaugh fc034270ce fix(core): call ngOnDestroy on all services that have it (#23755)
Previously, ngOnDestroy was only called on services which were statically
determined to have ngOnDestroy methods. In some cases, such as with services
instantiated via factory functions, it's not statically known that the service
has an ngOnDestroy method.

This commit changes the runtime to look for ngOnDestroy when instantiating
all DI tokens, and to call the method if it's present.
