- Add I210ToI420 to convert 10 bit 4:2:2 YUV to 4:2:0 8 bit
- Add NEON InterpolateRow_16 for fast 10 bit scaling
- When scaling up, set step to interpolate toward height - 1 to avoid buffer overread
- When scaling down, center the 2 rows used for source to achieve filtering.
- CopyPlane check for 0 size and return

When attempting to normalize function names to end in Row_SIMD it was made
harder with MIPS_DSPR2 naming convention.
Other CPUs do not include the vendor. This should be named consistently.
Removed the DISABLE_MIPS in favour of DISABLE_ASM for consistency with other
