Summary:
Problem: Certain turbo modules use the bridge to access JS directly by calling something like `[_bridge enqueueJSCall:]`. In a bridgeless world, this API no longer works.
Solution: These turbo modules can implement the new protocol defined here. This protocol provides a block during module init which can be used to call JS directly (using `ReactContext`) instead of going through the bridge.
Changelog: [Internal][iOS] - Introducing RCTJSInvokerModule, a new protocol for turbo modules which call js
