android/display: group the subpicture VOUT_DISPLAY_CHANGE_SOURCE_CROP/PLACE

VOUT_DISPLAY_CHANGE_SOURCE_PLACE is called when:
- crop changes
- aspect-ratio changes
- video area changes after a window size changes
- zoom changes
- the fitting of the video changes inside the window

We may force a place_changed when it actually didn't change.
But it only calls sub->api.vt.Viewport() which is cheap.
