This PR is meant to backport the changes in the #3745 to 0.59-vnext-stable, and hence to devmain immediately.

  1. Removing some pre-processing on systrace events before writing to ETW provider. We added them for easier analysis through WPA. BUt, We now have tool (JS HUD) which can process the raw events offline.
  2. Adding a unique id per Systrace section which allows us to match the start and end events.
  3. Some renaming and documentation on the macros for better readability.

Not directly related to this CR, but as a warning, high_resolution_clock can have unexpected behavior, like going backwards with things like daylights savings time. steady_clock won't do this, and is still implemented with QueryPerformanceCounter on Windows so you should get a high resolution.

Given devmain is already off of 0.59 and we've had some crash issues, I'm just going to close this.
