MouseArea example: use qt_add_qml_module() and update a signal handler

Thing patch updates the CMakeLists.txt file to use qt_add_qml_module()
instead of qt6_add_resource().

Additionally, it changes a signal handler, which was previously a plain
statement, into a js function, which is the preferred way to write signal
handlers.
