8512624a41 msdkenc: set ROI region for msdk{h264, h265}enc
A reconfig is needed when ROI is changed, otherwise the ROI parameters won't
take effect

e924dec4e1 msdk: h264_enc: Enable B-pyramid prediction support
Since there is already an "adaptive-B" option, just
use boolean property for B-pyramid enabling.

Fixme: Not sure whether this can be supported in vp8 and vp9.
It could be possible through GPB (b without backward ref) but
can't verify currently. We can move this as common property
once verified with vp8 and vp9 without breaking any backward
compatibility.

f25bcf7cb8 msdk: h264_enc: Add slice size tuning option
According to spec, it is a general property. But based on
testing it only works for h264 encoder.
Let's keep it as h264 specific for now.

b7dbcb26b8 msdk: encoder: h264: Enable trellis quantization tuning
Add a new property "trellis" to enable trellis quantization.
Keeping trellis as a flag value (which is boolean for gst x264 enc element)
since it is possible to enable/disable this seperately for
I,P and B frames through MediaSDK ext option headers.

The subclass implementations always need to inform base-encoder
if it requires the inclusion of Extend Header buffers (mfxExtCodingOption2
 and mfxExtCodingOption3).

d58c0bd509 msdk: h264_enc: Add LookaheadDownsampling support
This option controls down sampling in look ahead bitrate
control mode. According to spec it is only supported in AVC.

Fixme: Probably HEVC also have support for this in recent
MSDK versions. We could move the enumeration types to common
header usable for multiple codecs.

538aae2404 msdkh264enc: Implement frame-packing SEI insertion for side-by-side and top-bottom
Ideally this would be supported directly in the Intel MediaSDK but
that's not the case nowadays.
