[EventTiming] Improve some of the flaky tests

This CL improves crossiframe.html by waiting for the load event (so it
knows the iframe is ready), and makes it faster by awaiting for both the
main frame and iframe observers at the same time. It also improves the
buffered-and-duration test by considering cases in which the first event
does actually get buffered due to machine slowness.
