test: add tests for zimg RGB repacking
This tests the RGB repacker code in zimg, which deserves to be tested
because it's tricky and there will be more formats.
scale_test.c contains some code that can be used to test any scaler. Or
at least that would be great; currently it can only test repacking of
some byte-aligned-component RGB formats. It should be called
repack_test.c, but I'm too lazy to change the filename now.
The idea is that libswscale is used to cross-check the conversions
performed by the zimg wrapper. This is why it's "OK" that scale_test.c
does libswscale calls.
scale_sws.c is the equivalent to scale_zimg.c, and is of course
worthless (because it tests libswscale by comparing the results with
libswscale), but still might help with finding bugs in scale_test.c.
This borrows a sorted list of image formats from test/img_format.c, for
the same reason that file sorts them.
There's a slight possibility that this can be used to test vo_gpu.c too
some times in the future.
