Details

With the current API it's difficult for the user to know when the profiler actually started. There's 2 solutions to this:

1. return only when the profiler started.
2. return a promise that would be resolved when the profiler started.

I think Chrome is doing 1. (although I couldn't really get this to work in current Chrome versions). But because this isn't standardized and isn't supposed to be cross-browsers, and at this time and age, I think we should return a promise.

From :baku, we should file a spec bug in https://console.spec.whatwg.org/ before implementing this, if only to specify that this isn't supposed to be cross-browser, or that it should/shouldn't be exposed to web content.
