This function reads 2 byte values and writes the 2nd byte to the destination.
It turns out this is useful for P010ToNV12 as well, so adding the planar function allows a high level to call this.
And adds UYVY support for something YUY2 already had. Which is writing the 1st byte.

When doing 90 or 270 degrees rotation we need to do a rotate&scale of the UV planes, as there are no helper optimized functions to do this, we use the Y plane as temporal memory and perform each of the transforms independently:
First U plane is rotated, putting the result in the Y plane. After the rotation, the output has double the samples horizontally and half the samples vertically, so it is scaled into the final U plane. Same process is done with the V plane.
Last the Y plane that can be just rotated without scaling.
It would be great to have an optimized version for this, but maybe this is helpfull for triggering the discussions.
