libvideorender: CB2 show/hide video with new api [1/1]

PD#OTT-49451

Problem:
on drm plugin,if on pause state,we can hide video,but
can't show video again.because disable_plane flag will
destroy drm pipeline,if we want to show video,we should
send a new video frame to create pipeline.but we haven't
buffer to send to drm on pause state

Solution:
drm provides a new api for hide/show video feature
