video: remove some useless old RGB formats

Some VOs had support for these - remove them.

Typically, these formats will have only some use in cases where using
RGB software conversion with libswscale is faster than letting the
VO/GPU do it (i.e. almost never). For the sake of testing this case,
keep IMGFMT_RGB565. This is the least messy format, because it has no
padding/alpha bits with unknown semantics.

Note that decoding to these formats still works. We'll let libswscale
repack the data to whatever the VO in use can take.
