Avoid property name conflicts in event-emitter codegen (#36591)

Summary: Pull Request resolved: #36591 If any of the properties used in event-emitter codegen conflict with `event` or `payload`, the generated code will fail to build, even if this generated code isn't used. Since these are quite common keys, prefix them with `$` (still valid C++) to avoid conflicts.
