[iOS] Remove side effects from DevTools (swizzling, module exporting)

- Remove swizzling from dev tools
- Remove RCT_EXPORT_MODULE from RCTDevMenu

Do not use RCT_EXPORT_MODULE in RCTDevMenu

Because this class swizzles a system method inside `initialize`, all the versions of RCTDevMenu conflict with each other when we use RCT_EXPORT_MODULE because they are all referenced immediately at runtime.
