Android: enable tst_qqmlextensionplugin

The test was extracting plugins from the installation directory.
However on Android plugins can be read only from APK's libs subdir.
By default no plugins are copied into the APK, because they are not used.
So add a dummy.qml file which uses some basic stuff from Qt.Quick and
Qt.Quick.Controls. This will force the plugins to be copied into the APK.

Fixes: QTBUG-100169
Pick-to: 6.3 6.2
