Re: [performance-timeline-tests] New PerformanceObserver tests (#4660)

This adds tests for https://github.com/w3c/performance-timeline/issues/65, https://github.com/w3c/performance-timeline/issues/66,  https://github.com/w3c/performance-timeline/issues/67.

This uncovers a few issues in Firefox's implementation (sort + callback observe). As well as makes tests match the spec for disconnect behavior, which does not match Chrome's behavior. The this value checking also uncovers an issue in WebKit's [coming implementation](https://bugs.webkit.org/show_bug.cgi?id=167546).
