screencastService: Add gstreamer pipeline for h264 low-power hw encode

Browse Source 
VA-API low-power encoder profiles (such as vah264lpenc) reduce power consumption by relying entirely on fixed-function hardware blocks.
Use vah264lpenc over vah264enc by default, in order to save on energy and 3D engine capacity.
