Name the ScreenCaptureOutput

Set a name for ScreenCaptureOutput based on whether it's used for region
sampling or not and include the display's id if present.

In Output's mNamePlusId, drop " (NA)" for those without a display id.
This would be extraneous on the ScreenCaptureOutput, which will mark the
display for which it's being used.
