[api] Rename `global_reference` to `GlobRef.t` to follow kernel style.

In #6092, `global_reference` was moved to `kernel`. It makes sense to
go further and use the current kernel style for names.

This has a good effect on the dependency graph, as some core modules
don't depend on library anymore.

A question about providing equality for the GloRef module remains, as
there are two different notions of equality for constants. In that
sense, `KerPair` seems suspicious and at some point it should be
looked at.
