lavfi/scale_qsv: simplify scale_qsv filter
Use QSVVPPContext as a base context of QSVScaleContext, hence we may re-use functions defined for QSVVPPContext to manage MFX session for scale_qsv filter. In addition, system memory has been taken into account in QSVVVPPContext, we may add support for non-QSV pixel formats in the future. Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>
