[gnome-builder] libide: add ide_buffer_manager_get_buffers()

    libide: add ide_buffer_manager_get_buffers()
    
    This method will return a newly allocated GPtrArray with all of the
    loaded buffers as elements.
    
    Only a reference to the GPtrArray is returned (transfer container), but
    the container has a reference to the buffers.
    
    Simply release with g_ptr_array_unref().
