drm/amd/display: fill up DCN3 DPP color state
DCN3 DPP color state was uncollected and some state elements from DCN1
doesn't fit DCN3. Create new elements according to DCN3 color caps and
fill them up for DTN log output.
rfc-v2:
- fix reading of gamcor and blnd gamma states
- remove gamut remap register in favor of gamut remap matrix reading
