A repeat of the previous useless commits.
Pondered whether to use separate fields or just a flags integer for
color and component types; the latter won for now.
Functions like mp_imgfmt_get_component_type() are now discouraged, and
mp_imgfmt_desc.flags is back for defining all information. Some days ago
I felt like the opposite would be the better design. Fortunately, it
doesn't matter.
With this, I think all image format properties that mpv needs are
exhaustively defined all in one place.
