Remove inline docs for qt_import_plugins() to avoid duplication

Don't maintain two copies of the docs for qt_import_plugins() in
separate places. Remove the inline docs because they are not the
canonical ones that the user docs contain.

Also remove the TODO and qml plugins. Those are now handled by a
separate command, qt_import_qml_plugins(). Add a "see also" link to
assist in discoverability.
