fix(animations): Remove ɵAnimationDriver from private exports (angular#35690)

ɵAnimationDriver can be safely removed from private exports as AnimationDriver
is already a public export.  Since its already available, we can safely remove
its declaration and migrate its only usage in our repo to rely on the public
AnimationDriver symbol.

PR Close angular#35690
