Summary: Not having this disallows including turbo module and extending in places where RTTI is enabled. There is no additional includes or implementation changes - it merely allows for things to nicely link with other libraries. Changelog: [General][Fixed] - Allow including TurboModule.h in mixed rtti/no-rtti environment, even if TurboModule.h/cpp is compiled without RTTI.
