It also updates docs/meson-version.md to avoid this happening again.
The freedesktop SDK, which is used by gnome-build-meta, only has Meson 0.63. Bumping GLib’s Meson dependency to 0.64 means that, at the moment, GLib is not buildable in gnome-build-meta and hence can’t be tested in nightly pipelines against other projects, etc.
That’s bad for testing GLib.
It’s arguably bad that we’re restricted to using an older version of Meson than shipped by Debian Testing, but that’s a separate discussion to be had.
Revert the Meson 0.64 dependency until the freedesktop SDK ships Meson ≥
0.64. This also means reverting the simplifications to use of
gnome.mkenum_simple().
