This reverts commit fbea8c519684577a38cb35b9287ba4645a905094.
Reason for revert: Breaks WebRTC import into Chromium, e.g:
https://chromium-review.googlesource.com/c/chromium/src/+/3863998/
Original change's description:
> 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).
