Quick: Make sure the module initialization runs in static builds

We need to keep a reference to the module initialization function
somewhere in order to prevent the linker from removing it. In order to
avoid further littering of the namespace, the QQuick_initializeProviders
function is transformed to cover all of the initialization.
