One of the points of subprojects is to allow building against a version
of a dependency that the project has been tested against, so don’t try
and build against gtk-doc master. Building against master is actually
currently fine, but is a slight risk. Making this change also removes
one more instance of `master` from `git grep master` results, which
helps #2348.

Use the depth= argument from Meson 0.52 to limit the clone depth of
subprojects to 1. This should make the CI images a little smaller, and
reduce the bandwidth required to build them (although that’s not so
important because it only happens once every few months).
Similarly, only clone to a depth of 1 in `cache-subprojects.sh`, which
is run once every few months.

Now that we require Meson 0.52 to build the doc, we can also pull
gtk-doc as subproject when missing from the system. This requires
to pull gtk-doc master because needed changes there haven't been release
yet.
