Add beginning of input capture API
This API aims to provide a way for users to capture input devices under certain conditions, for example when a pointer crosses a specified barrier. So far only part of the API is implemented, specifially the session management as well as zone advertisement, where a zone refers to a region in the compositor which edges will eventually be made available for barrier placement. So far the remote access handle is created while the session is enable, despite the input capturing isn't actually active yet. This will change in the future once it can actually become active. v2: Remove absolute/relative pointer, keep only pointer (ofourdan) Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2628>
