Add Q_TRACE calls to QtQml for QML profiler trace points
This adds tracepoints for LTTng/ETW at the positions that are also
used by the QML profiler within QtQml. I.e. with the tracepoints
here, you'll see which QML function is being executed which is
already quite helpful.
This will allow us to bridge the gap between C++ and QML when
tracing with LTTng/ETW. Additionally, you'll also be able to see
kernel tracepoints which bridges another gap.
Combined, this approach can give much deeper insights into what the
(embedded) system is doing compared to just looking at the QML
profiler alone.
