PipeWire capturer: make use of ScreenCaptureFrameQueue

This allows us to keep always some frame around so we can return it
everytime consumer asks us to capture a frame as before we either
returned current frame or nothing as there was no new frame available.
This will be needed in order to support mouse cursor separately as
DesktopAndCursorComposer requires frame everytime, even if it's the
same one as before so we can combine it with the mouse cursor.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
