With Qt 6 in sight, people need to start moving away from
their deprecated APIs, as we want to remove them all in 6.0.
We are marking deprecated APIs with deprecation attributes,
but by default we're disabling deprecation warnings, making
them an opt-in by the user.

We need to do the opposite: make deprecation warnings enabled
by default, and have an opt-out define.

[ChangeLog][QtCore][Important Behavior Changes] Qt now
enables by default warnings when using APIs marked as
deprecated. It is possible to disable such warnings by
defining the QT_NO_DEPRECATED_WARNINGS macro. The old
QT_DEPRECATED_WARNINGS macro which was used to enable
this warning now has no effect (warnings are automatically
enabled).

This checks that intenalHwnd in QEventDispatcherWin32::remainingTime is
initialized. If calling remaningTime, before createInternalHwnd
is called, the timeout member in the WinTimerInfo struct is not
initialized and contains a random value. This adds a check for that and
in that case returns the requested timer interval as the timer has not
yet been started. createInternalHwnd is called on the first request to
process events.

It also adds a test for checking the remaining time. But the issue can
only be seen if solely running the remainingTimeInitial test in
tst_QTimer. If running the test along side another test the other
test likely calls processEvents indirectly, which hides the issue. I
don't know if this is an issue in practice (the bug has been there
for as long a the git history goes back, 2011), but it causes the
basic_chrono test to fail if run as the only test.

When using QMouseEvent::pos to change the position of a widget, the
widget may shift in a shaking motion. This is warned about in its
documentation. For example if the system has a bit of load, we might
receive multiple mouse move events from the OS, before QMdiSubWindow
gets the first move event. In that case the first mouse move is ok,
but subsequent move events, will use a ::pos value that now does not
make sense as the position of the window have changed. The fix is to
use QMouseEvent::globalPos.

Before this the remaining time in the two tests 'remainingTime' and
'basic_chrono' had to be within the interval [100,200]. This relaxes
that to [50,200]. This test seems to be failing a lot when staging
changes in gerrit. I can reproduce some of the problem when putting a
lot of load on my system and running the tests, then remaining time is
very random.

Also removes the blacklist of remaingTime on Windows and macOS, as
basic_chrono and remaningTime tests are basically the same. The
tests also fails on Linux some times in gerrit.

I was also thinking one could:

- blacklist both tests
- remove interval requirements; just check remaining time is [0,200]
- remove the tests

Sync with QXcbEventQueue thread by QWaitCondition instead
