swscale: Add support for NV24 and NV42
The implementation is pretty straight-forward. Most of the existing NV12 codepaths work regardless of subsampling and are re-used as is. Where necessary I wrote the slightly different NV24 versions. Finally, the one thing that confused me for a long time was the asm specific x86 path that did an explicit exclusion check for NV12. I replaced that with a semi-planar check and also updated the equivalent PPC code, which Lauri kindly checked.
