Set priority among various display devices

* When a non-WFD virtual display device (SSD/
screenrecord) is active along with
non-hybrid WFD solution(WFD faked on
external), give preference to non-hybrid WFD
device over non-WFD virtual display device.

* This is needed only in cases when WFD is
enabled via v4l2 rather than using VDS api's.
