    gitlab-ci: new build organization.
    
    Rather than having the whole Win32 cross-build into the 'gimp' stage,
    break the dependencies and GIMP-only builds in 2 stages.
    
    Since apparently we need to keep the same structure for the native and
    cross build (otherwise we don't get parallel builds; in other words, I
    didn't find the possibility to set separate pipelines up), I move babl
    and GEGL into the same 'dependencies' stage.
    
    Finally I remove the -base rules extended into actual jobs, except for
    `.gimp-base` (this is the only which makes sense as it is actually
    common to the meson and autotools build).
