Add OpenStep coercion support for non-OpenStep plist types

- Use PLIST_OPT_COERCE option to coerce PLIST_BOOLEAN, PLIST_DATE, PLIST_UID, and PLIST_NULL to OpenStep-compatible types (1 or 0, ISO 8601 strings, integers, and 'NULL' string)
- Add plist_to_openstep_with_options() function to allow passing coercion option (and others)
- Update plist_write_to_string() and plist_write_to_stream() accordingly
