This is in preparation for porting `GRegex` to libpcre2, which is
happening in !2529. It’s a big port, though, and specially rebuilding
the CI images to add libpcre2 for it is a pain.
Add libpcre2, and then !2529 can drop the old libpcre dependencies when
the port lands.

Rather than carrying the copylib around inside GLib, which is a pain to
synchronise and affects our code coverage statistics.
This requires updating the CI images to cache the new subproject,
including updating the `cache-subprojects.sh` script to pull in git
submodules.
It also requires adding `gioenumtypes_dep` to be added to the
dependencies list of `libgio`, since it needs to be build before GVDB as
it’s pulled in by the GIO headers which GVDB includes.
