Show self stacktraces frame values

Not sure where it would be best to have this but currently when looking at frame, we see on that frame the total CPU/Memory/etc... and the relative % of the total.

But we should also show:
- the value for that frame itself without counting childrens.
- The % of that self value respective to the total of the given frame or grand total.

In fact the current value is shown twice in the frame and the tooltip...

In the new flamegraph though

We show this self value and % but we should also show the % relative to the total of the current frame I believe 10% in the screenshot.
