Subject: [Lut HAL backend] implementation

- Add Lut in HWComposer::DeviceRequestedChanges
- parse lutProperties into overlayProperties
- Add a mapper <layer*, pfd> to store lut fd to avoid dup() ops if
  passing the fds into callees.
- SurfaceComposerClient::Transaction::setLuts interface

Bug: 329472100
Test: builds
Flag: NONE HAL backend interface change
