lavfi/scale_qsv: re-use VPPContext for scale_qsv filter

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
