Tracepoints: add tracing for QEvents
Add tracepoints in all the main codepaths for event handling:
* QEvent ctors/dtor
* QCoreApplication::postEvent, sendEvent and sendSpontaneousEvent
* QCoreApplication / QApplication::notify, and around the handling
of event filters as well
I'm switching the name of the tracepoints themselves to have the
very same casing of the functions in Qt's own source code, this
improves readability a lot. The pre-existing ones will be changed
in an upcoming patch.
