I010ToNV12 conversion using 2 step row function for UV

- convert full Y plane with row coalescing if possible
- convert rows of UV from 10 bit to 8 bit then call MergeUV

libyuv_test '--gunit_filter=*010ToNV12_Opt' --libyuv_width=3840 --libyuv_height=2160 --libyuv_repeat=1000 --libyuv_flags=-1 --libyuv_cpu_info=-1
Note: Google Test filter = *010ToNV12_Opt
