Set more predefined macros in the doxygen config. (#55900)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/55900

Doxygen incorrectly parses macros like `NS_DESIGNATED_INITIALIZER`,  `RCT_EXTERN`, `RCT_DEPRECATED`, `RCT_EXTERN_MODULE`, `API_AVAILABLE`. Setting them them as predefined empty string solves the issue.
