lavu/hwcontext_qsv: add loader field to AVQSVDeviceContext

Browse Source 
In oneVPL, a valid mfxLoader handle is needed when creating mfx session
for decoding, encoding and processing[1], so add loader field to
AVQSVDeviceContext. User should fill this field before calling
av_hwdevice_ctx_init() if using oneVPL

This is in preparation for oneVPL support
