Pieter De Baets 3a06cca9dc Add feature flag to use JSI NativeState instead of HostObject (#36395)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/36395

NativeState is a lighter-weight alternative to HostObject, which may simplify some of our use-cases of interacting with JS in the renderer. The down-side is that this approach doesn't allow exposing custom props or functions.

This diffs adds new feature flags to enable experimenting with this functionality and measure any perf impact.
