Even though drmhwc does not support per-layer LUTs, the vts test
GraphicsComposerAidlCommandV4Test.SetUnsupportedLayerLuts issues the
setLayerLuts command when the display is in headless mode with
vkms/cuttlefish. Since drmhwc ignores the command, the test fails.
Instead of ignoring the command, return a kUnsupported error which
allows the test to pass.

FlatteningController acquires its internal lock first, and then acquires

first, and will acquire the FlatteningController internal lock in

acquire the global lock in the SendRefreshEventToClient callback.

[Why]
Android requires a readback mechanism to validate display output,
especially in automated testing environments. This implementation is
particularly beneficial for writing automated tests with VKMS, as it
provides a reliable way to directly validate the rendered output.
[How]
Implement support for display readback using DRM/KMS writeback
connectors. This patch:
- Adds buffer management for readback operations
- Implements proper fence handling for both input and output operations
- Integrates with DRM atomic interface to configure writeback connectors
- Provides buffer readiness signaling to client applications
The implementation verifies hardware compatibility by finding matching
writeback connectors for displays and handles all resource lifecycle
management including buffer replacement and cleanup. This allows
tests to directly capture and verify the rendered output, ensuring
correctness and stability.
