   swscale/ops: allow excluding components from SWS_OP_DITHER
   We often need to dither only a subset of the components. Previously this
   was not possible, but we can just use the special value -1 for this.
   
   The main motivating factor is actually the fact that "unnecessary" dither ops
   would otherwise frequently prevent plane splitting, since e.g. a copied
   alpha plane has to come along for the ride through the whole F32/dither
   pipeline.
   
   Additionally, it somewhat simplifies implementations.

   swscale/ops_backend: implement support for optional dither indices
   If you place the branch inside the loop, gcc at least reverts back to scalar
   code, so better to just split up and guard the entire loop.

   swscale/x86/ops: split off dither0 special case
   I want to rewrite the dither kernel a bit, and this special case is a bit
   too annoying and gets in the way.

   swscale/x86/ops: don't preload dither weights
   This doesn't actually gain any performance but makes the code needlessly
   complicated. Just directly add the indirect address as needed.

   swscale/x86/ops: add support for optional dither indices
   Instead of defining multiple patterns for the dither ops, just define a
   single generic function that branches internally. The branch is well-predicted
   and ridiculously cheap. At least on my end, within margin of error.

   swscale/ops_optimizer: eliminate unnecessary dither indices
   Generates a lot of incremental diffs due to things like ignored alpha
   planes or chroma planes that are not actually modified.
   
   e.g.
   
    bgr24 -> gbrap10be:
      [ u8 XXXX -> +++X] SWS_OP_READ         : 3 elem(s) packed >> 0
      [ u8 ...X -> +++X] SWS_OP_CONVERT      : u8 -> f32
      [f32 ...X -> ...X] SWS_OP_SCALE        : * 341/85
   -  [f32 ...X -> ...X] SWS_OP_DITHER       : 16x16 matrix + {2 3 0 5}
   +  [f32 ...X -> ...X] SWS_OP_DITHER       : 16x16 matrix + {2 3 0 -1}
      [f32 ...X -> ...X] SWS_OP_MIN          : x <= {1023 1023 1023 1023}
      [f32 ...X -> +++X] SWS_OP_CONVERT      : f32 -> u16
      [u16 ...X -> zzzX] SWS_OP_SWAP_BYTES
      [u16 ...X -> zzzX] SWS_OP_SWIZZLE      : 1023
      [u16 ...X -> zzz+] SWS_OP_CLEAR        : {_ _ _ 65283}
      [u16 .... -> zzz+] SWS_OP_WRITE        : 4 elem(s) planar >> 0
        (X = unused, z = byteswapped, + = exact, 0 = zero)
