lavu/hwcontext_qsv: specify Shift for each format

Browse source 
We can't get Shift from bit depth for some formats in the SDK. For
example, bit depth is 10, however Shift is 0 for Y410 (XV30 in FFmpeg).
In order to support these formats in the next commits, this patch
specified Shift for each format
