build: Move gvdb to a subproject

Browse Source 
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.

<description xml:lang='en'>
A simple database file format that stores a mapping from strings to
GVariant values in a way that is extremely efficient for lookups.
The database is written once and can not be modified.
Included here is reader code and a first-pass implementation of a
writer (that does not currently produce particularly optimised
output).
It is intended that this code be used by copy-pasting into your
project or by making use of git-merge(1).
