PiP: Animate resize even if the bounds are the same.

On PiP resize animation, we have callbacks that show menu, set PiP to
the correct state, etc. Even if the bounds are the same (which is
possible if the user has resized the largest possible bound and taps on
it), we should still just let the animator do its job so all the
post-animation callbacks are correctly executed.

Bug: 158859217
Test: Resize PIP to max, wait for a new video to come in (current video
finishes playing), tap on PIP - menu displays
