Move i18n example to qttools

Move i18n example out of qtbase. In qttools, it can use lrelease, avoiding the need to store .qm files in the repository. Change-Id: I8ba36a1372c2a743b809e3f7ea95a67825558f41 Reviewed-by: Tor Arne Vestbø <tor.arne.vestbo@qt.io>

    \title I18N Example
    \ingroup examples-widgets-tools
    \brief The Internationalization (I18N) example demonstrates Qt's support for translated
    text. Developers can write the initial application text in one language, and
    translations can be provided later without any modifications to the code. It also
    demonstrates how to detect the system language settings and show the UI in the appropriate
    language.
