drm/amd/display: Add COLOR_ENCODING/COLOR_RANGE to overlay planes 



Extend COLOR_ENCODING and COLOR_RANGE property creation to overlay
planes in addition to primary planes. This allows overlay planes to
use YUV formats with proper color space configuration when the
hardware supports NV12/P010 formats.

These properties control the YUV-to-RGB conversion matrix selection
(BT.601/BT.709/BT.2020) and range handling (limited/full range).
