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.

So they are consistent with the way we’re building man pages in other
projects, and because some people are allergic to XML.
This changes the build-time dependencies from `xsltproc` to `rst2man`,
and also takes the opportunity to change the `-Dman` Meson option from a
boolean to a feature (so you should use `-Dman-pages={enabled,disabled}`
now, rather than `-Dman={true,false}`).

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.
It needs to be in a separate page because it’s all macros and they have
no type/class associated with them.

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.
As we start moving documentation over from gtk-doc to gi-docgen, the
gtk-doc coverage is going to go down and things are going to start
breaking. That’s OK; we don’t need to test it any more.

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.

There is currently no `dllimport` attribute on any of our function,
which prevents MSVC to optimize function calls.
To fix that issue, we need to redeclare all our visibility macros for
each of our libraries, because when compiling e.g. GIO code, we need
dllimport in GLIB headers and dllexport in GIO headers. That means they
cannot use the same GLIB_AVAILABLE_* macro.
Since that's a lot of boilerplate to copy/paste after each version bump,
this MR generate all those macros using a python script.
Also simplify the meson side by using `gnu_symbol_visibility : 'hidden'`
keyword argument instead of passing the cflag manually.
This leaves only API index to add manually into glib-docs.xml when
bumping GLib version. That file cannot be generated because Meson does
not allow passing a buit file to gnome.gtkdoc()'s main_xml kwarg
unfortunately.
This has the side effect of always rebuilding the doc at each build when
gtk_doc option is enabled (not by default). Most importantly, this will
enable doc check on our CI.
Those lists were getting very long. We can’t quite entirely automate the
list generation since Meson doesn’t have a range() function, but we can
at least combine three of them into one.

By default, only build man pages and gtk-doc if the build-deps were
found. To force-enable, pass -Dwith-docs=yes and -Dwith-man=yes.
Also use a foreach loop for man pages instead of listing them all
manually
