libavutil/pixdesc: fix prefix matching in *_from_name() functions
The seven *_from_name() functions in pixdesc.c (color_range,
color_primaries, color_transfer, color_space, chroma_location,
alpha_mode) used av_strstart() for prefix matching, which returns
incorrect results when one name is a prefix of another.
av_color_space_from_name("ycgco-re") matched "ycgco" at index
AVCOL_SPC_YCGCO and returned 8 instead of AVCOL_SPC_YCGCO_RE.
av_color_space_from_name("ycgco-ro") had the same issue. The
*_ext name lookups inside av_color_primaries_from_name and
av_color_transfer_from_name had the same flaw.
Switch all eight call sites from av_strstart() to strcmp() for
exact matching. No in-tree callers rely on prefix matching.
