Gwenole Beauchesne 59229b20a5 encoder: add keyframe period API.
Add gst_vaapi_encoder_set_keyframe_period() interface to allow the
user control the maximum distance between two keyframes. This new
property can only be set prior to gst_vaapi_encoder_set_codec_state().

A value of zero for "keyframe-period" gets it re-evaluated to the
actual framerate during encoder reconfiguration.
