Add low latency P-pyramid support to qsv. This feature relates to
command line option "-p_strategy". To enable this flag, user also
need to set "-bf" to 0. P-strategy has two modes "1-simple" and
"2-pyramid". The details of the two models refer to

Add transform_skip option to hevc_qsv. By enabling this option,
the transform_skip_enabled_flag in PPS will be set to 1.
This option is supported on the platform equal or newer than CNL.

q->extco3.TransformSkip is set to MFX_CODINGOPTION_ON when q->transform_skip is
-1, right ? TransformSkip is tri-state flag, we may set it to
MFX_CODINGOPTION_UNKNOWN when q->transform_skip is -1.
