hwc: Add support for Macro Tile feature
Macro tile is enabled only if all the conditions are met:
1. GPU hardware should support Macro Tiling.
2. MDSS hardware should support Macro Tiling.
3. USAGE flags shouldnt contain GRALLOC_USAGE_SW_READ_OFTEN and
GRALLOC_USAGE_SW_WRITE_OFTEN.
4. RGB 16bit and 32bit formats.
5. persist.hwc.macro_tile_enable flag should be enabled.
PRIV_FLAGS_TILE_RENDERED flag is added to indicate whether the layer
is rendered/composited in Macro Tiling or Linear format.
