Partially revert "Inline QTest::qSleep()"

This change partially reverts change
a0e0b51001edfc1c7aea113c472ce995efa833fd.

Replacing the QTest specific sleep function with QThread::msleep()
was not a good idea. The reason is that QThread::msleep() will force
the thread to sleep to x mseconds, even if a signal woke the thread
in the meantime.

This would cause qWaitFor() to not call processEvents(), in some cases,
leading to flakyness and test failures in tests that rely on timing,
such as the animation tests in Qt Qml.
