swscale/ops_dispatch: substantially refactor subpass compilation
Instead of a loop with fixed structure, this function now recursively calls
itself as many times as needed to satisfy all criteria.

This is absolutely needed for the upcoming refactor which will allow for
also splitting apart ops lists as needed to e.g. handle partially subsampled
ops lists, which may need a complex sequence of filtering and merge steps
to be fully satisfied.

This does modify the way in which subpasses are compiled slightly, in that
each new subpass first tried again un-split, rather than a single split
resulting in all subsequent passes being split as well. This is mostly a
benign change, though it might matter one day.
