[PATCH RFC v2 18/20] drm/vkms: Prepare pre_blend_color_transform() for post-blend pipelines

[Nícolas F . R . A . Prado]

As a preparatory step for supporting post-blend color pipelines in VKMS,
rename pre_blend_color_transform() to color_transform() and make it take
the first colorop instead of a plane state, so it can be shared by both
pre- and post-blend color pipeline code paths.
