swscale/ops_chain: replace SwsOpEntry.unused by SwsCompMask
Needed to allow us to phase out SwsComps.unused altogether.

It's worth pointing out the change in semantics; while unused tracks the
unused *input* components, the mask is defined as representing the
computed *output* components.

This is 90% the same, expect for read/write, pack/unpack, and clear; which
are the only operations that can be used to change the number of components.
