video: Add NV12_10LE40 pixel format

Browse source 
This pixel format is a fully packed variant of NV12, a luma
pixel would take 10bits in memory, without any filled bits
between pixels in a stride. The color range follows
the BT.2020 standard.

In order to get a performance in hardware memory
operation, it may expend the stride, append zero data at the
end of echo lines.
