feat: raw log file lenses and folding

[lcottercertinia]

Is your feature request related to a problem?

It would be nice to have a bit more interaction between the file and the log viewer

Describe the solution you'd like

1. show log total time in the file as a code lens?
2. A go to time line button from a specific log line which will open the viewer and highlight the element?
3. A way to go back to a specific line in the raw log from the calltree / timeline view?
4. Show the total + self time of a specific event takes when the line is hovered?
5. collapse and expand matching start and end events
