video/out/placebo/utils: add mappings from pl enums to mpv enums

mp_trc_to_pl, mp_prim_to_pl, and mp_levels_to_pl have forward but not
inverse mappings. This commit adds mp_trc_from_pl, mp_prim_from_pl, and
mp_levels_from_pl inverse mapping functions, which just map the enums
in the other direction.
