[ios][prebuild] add release/debug switch script

Fixes #T228219721

This commit adds the debug/release switch script like we have for rn deps and hermes for react-core prebuilt:

- Added script: replace-rncore-version-js
- Inserted script into React-Core-prebuilt podspec
- Updated rncore.rb with correct filenames
