avcodec/chroma: map AV_PIX_FMT_NV24/42 to VLC_CODEC_NV24/42
Added in 5de4f1d871d60886b9630531fa8c34cad13cc9dd, aka libavutil 56.27.100.
We require libavutil 56.31.100.

avcodec: rectify mapping to RGB8 chroma
libavutil defines it as:
packed RGB 3:3:2, 8bpp, (msb)3R 3G 2B(lsb)
which corresponds to VLC's `R332`, not `R233`.
Tested with the Linux `vivid` driver.

The previous `!= 0` was kept when the replacement to ARRAY_SIZE() was

avcodec/chroma. map RGB+x formats to RGB+0 chromas
The libavutil formats will always be mapped to the VLC chromas without
a mask. VLC_CODEC_RGB32 will still be masked to libavutil chromas when
the mask matches or loosely if no mask matches.

avcodec/chroma: prioritize RGB mapping with the same mask
If the mask corresponds exactly, we have an exact match. If the RGB source
has a mask but none of the RGB mapping uses the same mask, we map to
a close RGB format with a different mask.
It's better than using the first VLC_CODEC_RGBxx in the list if there's
one corresponding to the exact match.
Another option would be to move the VLC_RGB_ES() calls at the end of the
list.

codec: avcodec: fix mask mappings for 32 bits RGB
The macros can not handle alpha channel properly,
as it does not only requires reassigning channels
but shifting.
Mapping to/from RGB32 also loses alpha information.
We can not rely on AV native macros for this and
need to declare chroma with fixed alpha position
Could also modify the macro to add left or right
shifts parameters and even less readable for 2 chromas.
