hwcontext_dxva2: add mutiple supported formats

Add support for VUYX, YUYV422, Y210, XV30, P012, Y212, XV36.
The added formats work with qsv acceleration and will not have
impact on dxva2 acceleration(-hwaccel dxva2) since so far
these formats are still not supported by using dxva2 acceleration.

Hwupload and hwdownload can work with the added formats.
