hwc/copybit: Handle "R/B swap" for RGBA and RGBX color formats.

Browse Source 
1.Framework notifies HAL with "HWC_FORMAT_RB_SWAP" layer flag to handle
a limitation where R and B components were swapped in Rendering phase.
2.Add "R/B swap" in hwc query to enable framework to query for support
in display HAL, at run-time.
