Emmanuele Bassi 2d158da7a4 Move ATK inside GTK
This is a temporary move that aims to make GTK's accessibility support
independent of external components.

ATK has lived outside of GTK since its inception, as it was meant to be
a generic API implemented by different toolkits; that mostly failed, and
we're now stuck with an abstraction layer that doesn't really abstract
anything of value. What it did bring, on the other hand, was maintenance
burden, with changes being propagated across different projects—ATK,
GTK, and whatever accessibility layer implemented the bridge to ATSPI on
Linux. This complexity is completely unwarranted for the benefits it
gives us.

Ideally, we'd get rid of ATK entirely, and expose the accessility API as
part of the GTK namespace, but that is a fairly sizeable work, so we can
start from this step. The ATK namespace is maintained, similarly to how
we maintain the GDK, GSK, and GTK namespaces. The API is still public,
so that GTK and out of tree widgets can consume it.

The inclusion of ATK comes with the removal of the deprecated entry
points and types, as that's a good chance to begin the cleanup of this
mess of an API. Sadly, this also means we have to disable the a11y tests
for the time being, as they depend on rando API from 2002.

Another side effect of moving ATK in tree is that we cannot link to
atk-bridge on X11, as that will link to the out of tree ATK; this means
that accessibility is disabled on X11.
