This commit adds basic screen casting and remote desktoping functionalty. This works by exposing two D-Bus API services: org.gnome.Mutter.ScreenCast and org.gnome.Mutter.RemoteDesktop. The remote desktop API is used to create remote desktop sessions. For each session, a D-Bus object is created, and an application can manage the session by sending messages to the session object. A remote desktop session the user to emit input events using the D-Bus methods on the session object. To get framebuffer content, the application should create an associated screen cast session. The screen cast API is used to create screen cast sessions. One can so far either create stand-alone screen cast sessions, or a screen cast session associated with a remote desktop session. A remote desktop associated screen cast session is managed by the remote desktop session. So far only remote desktop managed screen cast sessions are implemented. Each screen cast session may have one or more streams. A screen cast stream is a stream of buffers of some part of the compositor content. So far API exists for creating streams of monitors and windows, but only monitor streams are implemented. When a screen cast session is started, the one PipeWire stream is created for each screen cast stream created for the session. When this has happened, a PipeWireStreamAdded signal is emitted on the stream object, passing a unique identifier. The application may use this identifier to find the associated stream being advertised by the PipeWire daemon. The remote desktop and screen cast functionality must be explicitly be enabled at ./configure time by passing --enable-remote-desktop to ./configure. Doing this will build both screen cast and remote desktop support. To actually enable the screen casting and remote desktop, the user must enable the experimental feature. See org.gnome.mutter.experimental-features. https://bugzilla.gnome.org/show_bug.cgi?id=784199
