hwc/copybit: Add Color layer support in MDP Copybit composition.
1. Color layer has a destination rectangle, RGBA color and plane
alpha. There is no gralloc buffer. Layer flag HWC_COLOR_FILL
denotes color layer. MDP BLIT happens via MDP_SOLID_FILL mode.
2. There is no color member in HWC layer, so RGBA color value is
passed via "tranform" member from framework to HAL.
3. Update HWC query to enable framework to query for Color layer
support in HAL, at run-time.
