tst_QTimer: Replace unconditional qWait()s with QSignalSpy
Where possible. Sometimes the replacement is QTRY_COMPARE instead. Also don't use QTestEventLoop directly when it can also be replaced with QSignalSpy use. Remove the TimerHelper class, since its uses can be done with QSignalSpy (and a lambda when remainingTime is checked). Although checking static single-shot timers still needs a target object, so use a stripped down version in those tests. remainingTimeDuringActivation() was not actually testing the repeating case, but single-shot case twice, so fix that. In the repeating case the remaining time is exactly 20 ms on my machine, but QEMU emulation seems to be slow enough for time to advance before the lambda is executed, so relax the conditions.
