OpenJDK system properties used to initialize default encodings and locales

A number of OpenJDK system properties that were not set before are now set. For example, on Windows™ the console encoding properties reflect the console charset. The default locale might be different from previous Semeru versions, and is now consistent with OpenJDK behavior. In particular, on macOS® the default locale reflects the control panel settings rather than the environment variable settings. The locale script is set when available.
