For top-level builds it's desirable to have "ninja generate_docs" build all tools needed to generate the documentation. This is problematic since the doc-generating targets are created before the doc tool targets. Thus, we must defer the dependency connection if the doc tool target is not yet available. This patch adds the functions qt_internal_defer_dependency and qt_internal_add_deferred_dependencies.
