Only exclude shade from capture on non-virtual displays

Browse source 
Virtual displays (AirPlay/Sidecar/DisplayLink) are themselves presented
to the physical monitor via screen capture. Setting sharingType=.none on
their shade would remove the dimming from the actual monitor, not just
from screenshots. Guard the opt-out with !isVirtual so DisplayLink etc.
keep dimming, while real displays using shade (e.g. Mac mini HDMI) still
get screenshot-clean dimming.
