Show overall CPU utilization (current functionality) and per-core utilization in CPU utilization graph

[JeremyMain]

Purpose is to identify when application CPU utilization is limited to a single core.

Current work in progress, each CPU utilization has a separate color within the general CPU color range.

zoom in on a portion you can see the individual CPU core utilization more clearly

I need to overlay the overall CPU utilization in a more prominent color

Longer 60m example

Cinebench R23, first with multi-core rendering, then a short period of single core rendering, finally OctaneBench 2020
