QReadWriteLock: fix data race on weakly-ordered memory architectures

Origin: upstream, https://code.qt.io/cgit/qt/qtbase.git/commit?id=4fd88011fa7975ce
Last-Update: 2025-12-14

The fix changes the relaxed load of d_ptr in lockFor{Read,Write} after
the acquire of the mutex to an acquire load, to establish
synchronization with the release store of d_ptr when converting from an
uncontended lock to a contended lock.
