It doesn't really make sense to try to create the X11 capturer if we are running under Wayland; nor does it make sense to create the PipeWire capturer if we are going to fail to actually start a stream with it. This change addresses both of these issues by exposing an IsSupported method on BaseCapturerPipeWire and checking that we are not running under Wayland before creating the X11 capturer.
