When loopback recording from a render device, the wasapi2src element captures audio even if the device is muted. This change adds the 'loopback-silence-on-device-mute' property that, when set to `true`, causes wasapi2src to inject silence in the pipeline when the device is muted. Fixes: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1306 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4337>
