sdm: Add rect mapping and interface to store actual resolution

1. Add rectangle mapping function to map a rectangle from one
   coordinate system to another coordinate system.
2. Add unaligned_width and unaligned_height in layer buffer to store
   the actual buffer resolution without alignment.
3. Populate unaligned width and height information of SDM layer
   buffer from private handle
