PiP: Re-attach PiP menu when display changes.

When changing the display (e.g. foldables that fold/unfolds) while the
menu is showing, it seems the SF layers go through some changes that get
the menu in a bad state and no longer renders correctly. Just teardown
and recreate/re-attach the menu instead.

Bug: 218987352
Test: Unfold/fold device while menu is showing, menu still shows up
afterwards
