gutter: port to GTK 4
- Use widgets instead of GInitiallyUnowned. This allows for much more
advanced usage of event controllers, snapshoting, and potentially
caching of render nodes.
- GtkSourceGutter is now a container of GtkSourceGutterRenderer
- Remove use of GdkEvent as much as possible and instead follow patterns
for events more closely to upstream GTK 4. In particular the query
and activate signals provide button/state/n_presses which are typically
what would be needed by renderers anyway.
- Tooltips can now be handled by renderers directly using the GtkWidget
infrastructure for that.
- Use GtkSourceGutterLines to reduce the number of passes we do through
the textbuffer btree. This helps achieve a few more frames per second
in the rendering pipeline during heavy kinetic scrolling. Especially
on HiDPI systems.
- Use GdkPaintable instead of GdkPixbuf for rendering pixbufs.
- Add alignment helper for renderers to center on a particular position.
This caches the positioning so that it can be reused by additional
cell renderers without the extra floating point math or view area
location.
- Renderer state is no longer necessary as that information can be
retrieved from the GtkSourceGutterLines using the helper functions.
State is simply a quark in the quarkset like any other status.

- * FIXME A better solution would be to add a vfunc in the
