Need to restore the following `TranslatePropertyNames` conversion option:
To rethink: should this option also affect the lowercasing of enum values, in addition to property names?
Note: when this option is turned on (by default), we to explicitly specify the original (Objective-C) name using@objcattribute: .
Done (restored this option for property names only; not for enum names).
