If a plugin gets disabled due to a `disabler()` dependency, the plugin
docs build itself will get disabled because `all_plugins_paths` will
become a disabler.
This was actually happening with opencv on systems that don't have
opencv available, and could happen with libsoup too if the build files
change in the future.
Let's avoid wasting hours of debugging for people. A not-found
dependency has the same effect.

Previously we were checking for opencv dep in 2 different places,
and the checks would vary in terms of how complex and exhaustive
they were.
Move the check into the libs module and reuse the result later on.

GLib guarantees libintl is always present, using proxy-libintl as
last resort. There is no need to mock gettex API any more.
This fix static build on Windows because G_INTL_STATIC_COMPILATION must
be defined before including libintl.h, and glib does it for us as part
as including glib.h.

... in favour of dep.get_variable('foo', ..) which in some
cases allows for further cleanups in future since we can
extract variables from pkg-config dependencies as well as
internal dependencies using this mechanism.
