Summary: Some ObjC NativeModules conform to `RCTInvalidating` protocol and implements `invalidate` method. This is typically used to clean things up during bridge teardown or reload. In TurboModule system the invalidate method can be replaced by pure destructors, but for backward compatibility, we call existing invalidate method on each module during teardown. This also cleans up all existing LongLivedObject's. Reviewed By: mdvacca, RSNara Differential Revision: D15365655 fbshipit-source-id: 802844b39b5b7adb54970ea541f4d744bbf9e480
