hwc: Add support for Macro Tile feature

Browse Source 
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.
