Subject: [PATCH] fix: check PipeWire init before creating generic capturer
 (#39846)

Check if PipeWire can be initialized before creating generic capturer.
This harmonizes the conditions with the ones used in Linux
implementations of DesktopCapturer::CreateRawScreenCapturer and
DesktopCapturer::CreateRawWindowCapturer.
