shell: Implement "driver" method of fullsceen.

Browse source 
Switching display mode may happen when:
1. The fullscreen surface is at top most in fullscreen layer and with
   "driver" method. Shell will switch output mode to match the surface
   size. If no matched mode found, fall back to "fill" method.
2. The top fullscreen surface is destroyed or unset. Switch back to the
   origin mode.
