sde: Add Support for UI/Video rotation using SDE rotator

1. Implement Buffer manager to allocate and deallocate output buffers
   for rotator.
2. Assign buffer slot for each layer requires rotation and manage the
   internal state of buffer slot in buffer manager.
3. Get the output buffer for each layer requires rotation from buffer
   manager and associate the information along with that layer.
4. Create/Destroy the rotator session from the hint provided by buffer
   manager. This is required to help driver to calculate the bandwidth
   for the current frame.
5. Validate the rotator configurations and submit the rotation job
   using rotator validate and rotator commit ioctl.
