Timer could have `start()`, `stop()` and `restart()` functions

[hunger]

Feature Description

As seen in Discussion #7435, the Timer object might benefit from some start(), stop() and restart() functions.

I think we can approximate them with setting the running property, but that might just pause the timer execution or do something different:-)

Makes sense. start() and stop() would be easy to implement by lowering to running = true/false
But restart would be harder because that's, i think, not possible right now and would need some extra generated code to do.
