really great work @lievenhey and sorry for the overly long delay in reviewing. there are only a few minor things left from the code POV, I'll now look at the CI failure and also test-run it locally a bit

QByteArrayLiteral or just compare to a string literal? your code forced an unneeded allocation

only used by formatTracepoint, so this can move to the .cpp file (into an anon namespace there?)

The tracepoints are getting a better visual representation on the timelinewidget so this is no longer necessary.
Move the tracepoints from TimeAxisHeaderView to TimeLineWidget so that we can use the header for cpu usage. This also improves usability since the tracepoints are no longer bundles in one line. They now each have their own line.
Enum automatically counts up so there is no need to manually set these values.
this allows the user to group important timelines together so that he can compare them better
The favourites and tracepoint patches include some rows in the model that may be empty. To keep the code simple an readable all rows will be shown. Then a proxy model is put ontop to remove empty rows.
This way we can more easily find them and changing the sort order doesn't move them to the bottom.
Showing only one cost is fine if we only show a hardware event, but since we now support tracepoints and some come in an enter/exit pair it requires us to rework the timeline delegate. This patch makes the event source combobox multi select and allows to select multiple event sources.
This patch allows hotspot to correctly parse most format string from the tracepoint definition. If that fails every entry in the tracepoint will be printed unformatted. In this case it is possible to add a custom formatter.

This PR expands the tracepoint PR to show additional information when hovering over a tracepoint.
This requires the perfparser PR to be merged.
This is still wip. The following things are planned:
