fix(core): remove core animation import symbols (#22692)

This patch removes the deprecated support for animation
symbol imports from @angular/core.

BREAKING CHANGE: it is no longer possible to import
animation-related functions from @angular/core. All
animation symbols must now be imported from @angular/animations.
