Drop gobject-introspection

[yselkowitz]

GObject Introspection has been merged (with a new library version and renamed tools) into the glib sources. While the original standalone version is still a dependency of some components and will continue to be pulled in as a result, it will presumably go away.

Migration to glib's GI involves a few steps:

1. Changing build tooling to use the new tools
2. Migrating libgirepository-1.0 consumers to libgirepository-2.0
3. Dropping or migrating use of the miscellaneous GIRs still provided in the g-i sources (DBus, GL, cairo, x11, etc.)
4. Dropping no-longer-used dependencies on gobject-introspection[-devel].

Core GNOME components should have already done (1) and (2), and are up to (3) or even (4). Other consumers may still need to be migrated.

AFAICS the most common case of (3) is cairo. cairo includes a gobject bindings now, so perhaps the GIR can be moved (or even better, generated) there?

Thank you Yaakov for putting this together! Looking at the list the PackageKit is not expected to be shipped in RHEL 11 (replaced by dnf-daemon). But the rest apart from system-config-printer is under the Display Group's control. I will create an internal ticket for this.
