gralloc: Use only metadata for color space

Browse Source 
Currently both handle metadata and handle flags are used to indicate
the color space. This change deprecates support for flags.

Also gralloc doesn't set a color space based on use case anymore,
since front-end requirements keep changing. The default is set to 601
and the onus of correctly specifying the color space now rests on
clients.
