[ios][prebuild] simplify logging in prebuild scripts

To reduce reduntant code by repeating the logging functionality in each JS module, this commit introduces a factory for creating a logger with a given prefix.

- Create factory `createLogger`
- Remove redundant log implementations
- Changed to use factory in hermes.js and ios-prebuild.js
