display: Add color Metadata

- Add color aspects and HDR10 related static metadata
  which will be used in the existing metadata structure.
- Clients can use COLOR_METADATA to update the CSC
  information
- UPDATE_COLOR_SPACE is legacy and will be used when
  COLOR_METADATA is not set.
- Update gralloc to return color space when set from
  COLOR_METADATA
- Gaurd the usage with USE_COLOR_METADATA for cobalt.
