The `gi-docgen` tool is not designed to be used like that. In
particular, when nesting documentation directories, the generated
`*.devhelp2` files (needed by Devhelp to show the documentation) are
nested one directory level too deep for Devhelp to find them, and hence
are useless, and the documentation doesn’t show up in this common
documentation viewer.
So, change the installed documentation directory hierarchy:
* `${PREFIX}/share/doc/glib-2.0/gio` → `${PREFIX}/share/doc/gio-2.0`
* `${PREFIX}/share/doc/glib-2.0/glib-unix` →
`${PREFIX}/share/doc/glib-unix-2.0`
* `${PREFIX}/share/doc/glib-2.0/gobject` →
`${PREFIX}/share/doc/gobject-2.0`
* etc.
* `${PREFIX}/share/doc/glib-2.0/glib` → `${PREFIX}/share/doc/glib-2.0`
This is going to seem like pointless churn (the contents of the
documentation have not changed), and packagers may mourn the split of
content in `/usr/share/doc` from `/usr/share/doc/${package_name}` to
`/usr/share/doc/${pkg_config_id}` instead, but that seems to be the best
approach to fix this issue in GLib. gi-docgen’s behaviour does feel
fairly consistent and correct with the rest of how it works (single
output directory).

Now that the reference documentation uses gi-docgen, it's more
troublesome to generate in less standard build scenarios like
cross-compiling.
In distributions like Debian, reference documentation is generally
packaged separately (in libglib2.0-doc in Debian's case), but man pages
are generally packaged alongside the executables themselves (in the
libglib2.0-bin and libglib2.0-dev-bin packages, in Debian's case). We
can exclude the reference documentation when cross-compiling, but ideally
we would like the man pages to still be built, so that a cross-compiled
libglib2.0-bin or libglib2.0-dev-bin package has the same content as a
native build.

They are now installed to (e.g.)
`${prefix}/share/doc/glib-2.0/{glib,gmodule,gobject,gio}/index.html`.
We might want to drop one level of nesting out of that, but for the
moment I thought I’d keep it in so we can disambiguate by installed
major version.

The GIR files are now built by GLib itself, so they will be in the build
directories of each sub-library, except for GLib-2.0 which is built
alongside GObject-2.0.
Gate the API reference on the availability of the introspection data as
well, so we don't accidentally try and generate the documentation
without a description of our API.
The files here are copied from the docs-gtk-org
branch of gtk.
This adds gi-docgen to the CI Dockerfiles and ensures the new versions
(including the OS upgrades from the previous commit) are used during CI.
