libavcodec/qsvenc: expose only supported options

vp9, hevc, avc, mpeg2 QSV encoders inherit common list
of options (QSV_COMMON_OPTS) while bunch of options is not
actually supported by current qsv code. The only codec which
supportes everything is avc, followed by hevc, while vp9 and
mpeg2 significantly fall behind. This creates difficulties
for the users to use qsv encoders. This patch fixes options
list for encoders leaving only those which are actually
supported.
