sdm: Add support for dynamic layer mixer resolution change.

1. Define binder API to change layer mixer resolution.
2. Honor layer mixer resolution change request only if the hardware
   supports destination scaler.
3. Give preference to panel scaling over destination scaling, as panel
   scaling requires less bandwidth.
4. Disable partial update for a frame on mixer resolution change.
