Handle right clicked markers in the UserTimings in the stack chart

The current architecture of the right clicking makes it difficult to have one chart that handles both call nodes and markers. This is because of the way the markers use an "id" to trigger showing the context menu, and needing to embed a trigger component. I think it would be better to have a single context menu trigger that can handle both the call nodes and markers, then have a connected component decide which one to show. This would simplify the triggering method, and make it easy to do both in one chart.

I recommended not doing this initially with #2345, but it should be a follow-up for this feature. Currently the stack chart does not support right clicking markers.
