Add plumbing to control PipeWire picker visibility

Introduces the notion of a "delegated source list" and corresponding
controller. This is used by desktop capturers (currently just the
PipeWire capturer), who control selecting the source through their own
(often system-level) UI, rather than returning a source list with all
available options that can then be selected by the embedder.

Adds a method to get the controller which serves to also tell embedders
if the capturer makes use of a delegated source list. The controller
currently allows the embedder to request that the delegated source list
be shown or hidden, and will in the future be used to expose events
from the source list (e.g. selection, dismissal, error).

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
