HWC: Add a color transform attribute per display
Adds a color transform option to the queryable display attributes,
which allows a different vendor-specific color transform (e.g., wide
gamut, sRGB, etc.) per display configuration. This does not increase the
HWC version, and is considered a part of HWC 1.5, though if
getDisplayAttributes returns an error code as a result of being passed
an unsupported attribute, the call will be retried without the new color
transform option.
