PerformanceObserverInit.buffered Per #18108, add `buffered` flag in the `PerformanceObserverInit` dict. Per W3C spec, when `buffered` is set, `PerformanceObserver.observe()` method adds the entries buffered in the `Performance` instance into the observer's entry buffer. One step is the implementation of the [filter by name and type](https://w3c.github.io/performance-timeline/#filter-buffer-by-name-and-type) algorithm. Don't think that the sort operation is useful in this case, but the spec states that this algorithm is to be used. - [X] `./mach build -d` does not report any errors - [X] `./mach test-tidy` does not report any errors - [X] These changes fix #18108 - [X] These changes do not require tests (yet) because the timeline API is not powered. <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/servo/18176) <!-- Reviewable:end -->
