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. Change-Id: I2c698007c1689779fe86d549093bb5285432dc5f
