backends/native: Add color space and HDR metadata updates

Browse Source 
Allows to prepare KMS updates to set the color space and HDR Static
Metadata on the output.

For some reason we need ALLOW_MODESET on commits which change the HDR
Static Metadata InfoFrame on AMDGPU. There is no technical reason why
one needs to mode set to send an InfoFrame and the driver should just
manage without ALLOW_MODESET. Until this is resolved in the kernel we
just prepare KMS updates which might mode set.
