lavfi/scale_qsv: re-use VPPContext for scale_qsv filter

Browse Source 
QSVScaleContext and VPPContext have the same base context, and all
features in scale_qsv are implemented in vpp_qsv filter,  so scale_qsv
can be taken as a special case of vpp_qsv filter, and we may use
VPPContext with a different option array, preinit callback and supported
pixel formats to implement scale_qsv then remove QSVScaleContext
