Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/36152 [Changelog][Internal] By [the W3C standard](https://developer.mozilla.org/en-US/docs/Web/API/PerformanceObserver/observe), `PerformanceObserver.observer` can optionally take a `durationThreshold` option, so that only entries with duration larger than the threshold are reported. This diff adds support for this on the RN side, as well as unit tests for this feature on the JS side. NOTE: The standard suggests that default value for this is 104s. I left it at 0 for now, as for the RN use cases t may be to too high (needs discussion).
