Rollout TurboModuleBinding::Prototype
Summary: We ran an experiment to test different implementations of TurboModules HostObjects, as the current one has various inefficiencies, such as re-creating HostFunctions on every property access. The strategy we found to be most efficient and flexible longer-term is to represent the TurboModule with a plain JavaScript object and use a HostObject as its prototype. Whenever a property is accessed through the prototype, we cache the property value on the plain object, so it can be efficiently resolved by the VM for future accesses.
Changelog: [General] TurboModules are now exposed to JS as the prototype of a plain JS object, so methods can be cached
