It’s not particularly necessary, and makes the build-time dependencies
more complex than they need to be, as it means that to generate
GLib-2.0.gir and GObject-2.0.gir, libgio.so (and its generated headers)
already needs to have been built.

These changes need to be replicated in gobject-introspection.git before
the problem can be solved, though, as that still has its own copy of
`gdump.c` (which it installs and uses).

These are all custom-written, including a load of research in `git log`
to find the copyright holders for `girepository/meson.build` and
`girepository/gi-dump-types.c`.
With this, `reuse lint` raises no complaints about the `girepository/`
directory.
