Gets an instance.

\l QIcon::setFallbackThemeName() should be called before QGuiApplication is created, to avoid a race condition (QTBUG-74252). When this function is called from there, ensureInitialized() does not succeed because there is no QPlatformTheme yet, so systemThemeName() is empty, and we don't want m_systemTheme to get initialized to the fallback theme instead of the normal one.
