QRandomGenerator: optimize the global() and system() storage
We store both in a single memory structure, instead of two local
statics. By construction, we also ensure that the global PRNG mutex is
in a different cacheline from the global PRNG state itself.
Finally, we don't store the full system QRandomGenerator, since we only
need the type member from it.
