    gtk4.pc: Move third-party libraries from Libs to Libs.private
    
    This avoids "overlinking". These libraries are an implementation detail
    of particular backends, so they only need to appear on library consumers'
    linker command-lines if the dependency cannot be picked up from the
    shared library automatically (when linking statically, or when building
    on a deficient OS that doesn't support transitive dependencies between
    shared libraries, in which case pkg-config should be built with
    --enable-indirect-deps).
