I210ToI420, InterpolatePlane_16, and ScalePlane Vertical-only asan fix
- 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
