Move PiP window upon tabletop mode changes

Browse Source 
System property persist.wm.debug.enable_move_floating_window_in_tabletop
can be used to toggle the feature.

Further, System property persist.wm.debug.prefer_top_half_in_tabletop
can be used to control which half is preferred. This preferred location
is used for moving the PiP and affects the default position as well.

This feature depends on the keep-clear-area experiment.
