Fixing issue with IME not showing after PiP menu is shown.

- Because the PiP menu activity needs to be always-focusable, it would
  always be found as the input focus target even after the menu is
  animated away.  This CL ensures that main activity window is hidden
  when the menu is also hidden so that we don't prevent the new focused
  app windows from getting focus
- This also allows us to not finish the activity when accessibility is
  enabled as the hidden window will not be reported to accessibility
  services
