swscale/uops: add ff_sws_shuffle_mask() helper
This takes an arbitrary shuffle mask and expands it out to the needed number
of bytes by repeating pixels.

I decided to have the implementation live in ops_optimizer.c to locate
it closer to the code where these shuffle masks are generated, to aid
in understanding, and because the optimizer will itself use it (in the
following commit).
