swscale/uops: add SWS_UOP_LINEAR_FMA and SWS_UOP_FLAG_FMA
This is like SWS_UOP_LINEAR but parametrized by which matrix entries can use
FMA instead of bitexact IEEE mul/add instructions.

I decided to make these a separate uop to avoid bogging down the reference
backend with arch-specific details like FMA. However, I think FMA ops are quite
common/universal so I pre-emptively split it into its own separate flag rather
than defining something like SWS_UOP_FLAG_X86.
