Generate localized_types_map.cpp from LocalizableTypes.strings

This script converts the iOS LocalizableTypes.strings file format to the desktop
localized_types_map.cpp C++ map by:
- Removing comments (/* ... */)
- Removing empty lines
- Converting from "key" = "value"; format to key=value format
- Removing unnecessary quotes and spaces
