Activity colouring depending on HEC usage

Intel VTune have similar profiling information which is helping to find places where not all available cores (HECs) are used.
The idea is to use tri-color/semaphore (red, yellow, green) to paint the activity diagram depending on HEC usage. For example, if activity is less than 50% it's red, less than 75% yellow and more - green. So programs are pushed toward more parallel computations.

Actual HEC activity could be painted, too.

首先定位活动图的渲染部分，以及暴露 HEC 使用情况的 profiling 数据路径。检查当前如何计算活动百分比，然后定义 issue 中描述的红色、黄色和绿色阈值，并确定是否有实际的 HEC 活动可用。当图表能够一致地反映这些阈值以及任何可用的 HEC 活动时，即表示完成。

由索引模型根据 Issue 内容生成。
