Subject: [PATCH] QThreadStorage: replace QScoped- with std::unique_ptr

This only affects the !QT_CONFIG(thread) case and requires the rewrite
of the old-style static cleanup() deleter protocol into the modern
operator()() one.

As a drive-by, mark the deleter noexcept, like destructors are
supposed to be.
