Add MetaKmsCrtc to represent a CRTC on the associated device. Change MetaCrtcKms to use the ones discovered by the KMS abstraction. It still reads the resources handed over by MetaGpuKms, but eventually it will use only MetaKmsCrtc. MetaKmsCrtc is a type of object that is usable both from an impl task and from outside. All the API exposed via the non-private header is expected to be accessible from outside of the meta-kms namespace. https://gitlab.gnome.org/GNOME/mutter/issues/548 https://gitlab.gnome.org/GNOME/mutter/merge_requests/525
