Fixes for iOS build

Tested:
- Windows build
- Android (Old Arch) build on Windows
- iOS (Old Arch) build

Presumably works:
- Android (Old Arch) build on Ubuntu
- Android (New Arch) build on Ubuntu

Broken:
- Android (New Arch) build on Windows; but I believe, it is due to
  bugs in React Native itself, at least I found and filed a bug in
  Codegen: facebook/react-native#36475
  and even with that bug fix, the build still fails later, seemingly,
  due to some other bugs in RN (New Arch) on Windows build host.

To be tested:

- iOS (New Arch) build
