videoflip: Add support for 10/12bit planar formats
Implements support for more formats: I420_10LE, I420_10BE, I420_12LE, I420_12BE, I422_10LE, I422_10BE, I422_12LE, I422_12BE, Y444_10LE, Y444_10BE, Y444_12LE and Y444_12BE
. Largely mimics the existing code, just adapted for up to 16bit per component and some changes in case of 4:2:2
subsampling.
