Support new GraalVM for JDK17/JDK20 release

This commit adds support for the new GraalVM for JDK17/JDK20 release, including the new Oracle GraalVM distribution.
For this, users only need to specify the 'java-version' option and the new 'distribution' option.
The 'version' option is now marked as optional and kept for compatibility with older GraalVM releases and Mandrel.
