[Profiler] Timeline UI Performance Regression

Profiling

-

With the change to allow for scrolling and resizing the threads in the Timeline view of the profiler came a performance regression. Since there was a change in the logic of how this is displayed, this is somewhat expected but particularly the way in which the maximum thread depth is calculated is suboptimal and can be a bit costly.

How to Reproduce:
1. Deep Profile the editor while looking at the CPU timelineview of the profiler
2. continuously press the "Current" button
3. stop profiling and examine the result of the profiler
