Strip `__deprecated_msg` in the preprocessing (#55970)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/55970

Strips `__deprecated_msg` annotations due to incorrect parsing when in front of the interfaces (predefining does not help unfortunately). It doesn't fully solve the issue stated in the added test as doxygen also has problem with parsing interfaces for which the base class is in the new line.

```
interface Foo
           : Bar<NSObject>
end
```

This will be handled by the fix in the doxygen.

This diff also adds stripping the `__deprecated` label which is again incorrectly parsed by doxygen.
