autoreconf: integrate gtkdocize into the standard reconfiguration tools

When the GTK_DOC_CHECK macro is in use, this flags a given configure.ac
as belonging the the common class of gtk-related software that requires
the gtkdocize tool to be run before autoreconf, in order to install the
gtk-doc macro and Makefile fragment. Make this easier to accomplish via
teaching autoreconf how to detect and run this tool automatically; this
gets us one step closer to a world in which `autoreconf -fi` on its own
is enough to bootstrap any autotools project into a configurable state.
