Make PerformanceObserver report correctly supported performance entry…

… types (facebook#39951) Summary: ## Changelog: [Internal] - This makes PerformanceObserver API more robust in regards of telling which exactly types of the performance entries are supported. At this point, we either tell that we support mark/measure/event ones on the New Architecture, or none otherwise. The source of truth of this information should be on the native side.
