Tests user timing events in traces.

Below offsets and startTimes are rounded to avoid flakiness on the bots.
FYI: startTime in args is the equivalent DOMHighResTimeStamp.
Marks:
ph name offset from ~zero args
I ~zero 0 ms {"data":{"navigationId":"xNavIdx","stackTrace":[{"columnNumber":34,"functionName":"pageFunction","lineNumber":3,"scriptId":"5","url":""}],"startTime":0}}
I @500 500 ms {"data":{"navigationId":"xNavIdx","stackTrace":[{"columnNumber":17,"functionName":"pageFunction","lineNumber":9,"scriptId":"5","url":""}],"startTime":500}}
I @1000 1000 ms {"data":{"navigationId":"xNavIdx","stackTrace":[{"columnNumber":17,"functionName":"pageFunction","lineNumber":8,"scriptId":"5","url":""}],"startTime":1000}}
I @1200 1200 ms {"data":{"navigationId":"xNavIdx","stackTrace":[{"columnNumber":17,"functionName":"pageFunction","lineNumber":7,"scriptId":"5","url":""}],"startTime":1200}}

Measures:
