Support YUYV and UYVY packed 4:2:2 raw input

Packed YUV is arguably more common than planar YUV when dealing with raw
4:2:2 content.

We can utilize the existing plane_copy_deinterleave() functions with some
additional minor constraints (we cannot assume any particular alignment
or overread the input buffer).

Enables assembly optimizations on x86.
