avfilter/vf_scdet: expand format list

Browse Source 
This filter works by running the SAD function on the first plane, which
works for any (native endian) format that starts with an unshifted luma
plane. This notably includes formats like nv12, yuva420p, and grayscale
formats, as well as luma-alpha formats. The last addition is debatable,
but the precedent here is the existing support for RGBA, which also
dilutes scene scores by including the alpha component in the SAD
calculation). There were also some notable missing packed RGBA formats,
such as ARGB, as well as 16-bit variants.

This is an exhaustive listing as of the current set of formats.
Tested by looping over `format=<pixfmt>,scdet` and verifying that the
scene SAD score doesn't (meaningfully) change, except for expected
deviations (e.g. larger scores for full range vs limited range, and
lowered scores for packed alpha formats).
