Parses a string containing a UI definition and merges it
with the current contents of @builder.
This function is useful if you need to call
[method@Gtk.Builder.set_current_object] to add user data to
callbacks before loading GtkBuilder UI. Otherwise, you probably
want [ctor@Gtk.Builder.new_from_string] instead.
Upon errors %FALSE will be returned and @error will be assigned a
GError from the %GTK_BUILDER_ERROR, %G_MARKUP_ERROR or
%G_VARIANT_PARSE_ERROR domain.
It’s not really reasonable to attempt to handle failures of this
call. The only reasonable thing to do when an error is detected is
to call g_error().
