Summary:
Xcode 10.2 forbids creating categories for swift class that uses `+load` method. In react-native categories like this are used to register swift classes as modules (macro `RCT_EXTERN_MODULE`) This PR changes it to use `__attribute__((constructor))` instead of objc `+load` method.
I introduced new macro for this purpose, `RCT_EXPORT_MODULE_NO_LOAD`, it expands in something like:
```
void RCTRegisterModule(Class);
+ (NSString *)moduleName {
return @"jsNameFoo";
}
__attribute__((constructor)) static void initialize_ObjcClassFoo{
RCTRegisterModule([ObjcClassFoo class]);
}
```
Functions marked with `__attribute__((constructor))` are run before main and after all `+load` methods, so it seems like correct thing to do.
