Move PIP/MW mode callbacks to be on the client side

We now infer the PIP/MW mode change from the new configuration.
Note also that both
- Activity#isInPictureInPictureMode
- Activity#isInMultiWindowMode
infer the current state from the configuration rather than querying
against the WM.

Also in this CL:
- When in removePinnedStackInSurfaceTransaction, keep the pinned stack
hidden till the windowing mode is set to fullscreen, this is to surpress
the attempt to set the activities to be started in reparenting
- When in ActivityRecord#shouldBeVisible, should take account the force
hidden flag, which is not actually in use before
