Measuring CPU utilization / scheduler statistics

[digitalentity]

I'm wondering whether there is a simple way of measuring the CPU utilization?

In other words - what fraction of time the scheduler is doing nothing, waiting for goroutines, timers, sleep or IO - essentially in waitForEvents() or sleepTicks() in case of the cooperative scheduler.

We do not have this functionality right now. It would certainly be interesting to have! Adding this to TinyGo without increasing binary size when this feature isn't in use will be somewhat challenging.
