kms/connector: Make property ID fetching more declarative
Instead of relatively verbosely going through the DRM properties finding the properties we care about and saving their ID's, add a more declarative way to fetch property metadata. This'll allow for fetching more property IDs with relatively less code, which will be useful for the atomic backend. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1488>
