[HWC] Add setLayerFloatColor API into HAL.

This patch:

1. Adds setLayerFloatColor API into HAL to enable setting more bits of color on
ColorLayer;
2. Adds VTS tests for setLayerFloatColor.

BUG: 69970838
Test: adb shell /data/nativetest/VtsHalGraphicsComposerV2_2TargetTest/VtsHalGraphicsComposerV2_2TargetTest
