Summary: Makes sure that we don't spam too often the JS performance entry reporting callback, which further dispatches entries to `PerformanceObserver` instances. The logic is as following: * ~~~If internal buffer of entries reaches the limit, we schedule the callback (with background priority)~~~ *~~~ Once the callback is processed, we schedule the next flush after a timeout of 500ms, this will also be scheduled from native with background priority~~~ * ~~~Whenever new performance type starts to be observed, we also schedule the callback, in order to prime the above~~~ * Schedule the flush with low priority, whenever there is the first entry coming into an empty buffer, and rely on the Scheduler to "do the right thing" when asked to flush it with background priority and not doo it exceedingly often (see the prolonged discussion) Changelog: [internal] Reviewed By: rubennorte Differential Revision: D41875085 fbshipit-source-id: 368b525203215350ceabb43d5e9e8e3bd5242aca
