Do not start VrManagerService if VR is not supported

When VR mode is not supported by removing the feature of
android.hardware.vr.high_performance, do not start VrManagerService.
Otherwise, there will be undesired behavior, such as calling into
PowerHal/VrHal for VR hints.

Test: no undesired behavior observed
