QReadWriteLock: add tryLockForXxx overloads taking QDeadlineTimer
This propagates inside the internals, ending up in wait_until calls in
the internal std::condition_variable. For systems with proper support
for monotonic waiting (Linux, FreeBSD), this should improve performance.
We could even remove the hasExpired() check and pass a time point in the
past too. Right now, there's a minor performance drawback for
tryLockForXxxx(), because we will make at least two system calls to get
the time.
