Glib subproject git checkout isn't cached any more on the
GStreamer CI image, so use tarball for now, and update to
more recent glib.
This means we can no longer use --default-library=both on
Windows, so add separate jobs for static/shared build.
Don't ship wrap files for things that are only dependencies
of dependencies, such as gperf (for fontconfig), or
libffi + proxy-libintl (for glib).
Instead, let Meson use the wraps that these subprojects ship,
which Meson will pick up automatically since v56, so there's
no need for us to ship these wraps any more.
Bump the Meson requirement to 0.56 accordingly.
Fix expat package dep for fedora ci and bump the tag so it gets
picked up.

fontconfig has changed its default git branch from
master to main, and deleted the master branch. This
breaks GTK ci on MacOs, where we use build cairo and
use its fontconfig subproject.
Update fontconfig wrap to upstream now that it's been merged.
Add gperf wrap which is needed for fontconfig, same as in the
upstream fontconfig repo (this can't be put into wrapdb yet
because it requires changes to source files).
