[jdk23u] RFR: 8335912: Add an operation mode to the jar command when extracting to not overwriting existing files

Tue Nov 19 02:24:24 UTC 2024

Please review the JAR tool enhancement.
It allows suppressing the overwriting of existing files with a new cmd line option.
The backport is almost clean except of src/jdk.jartool/share/classes/sun/tools/jar/GNUStyleOptions.java line 264
OptionType.EXTRACT was defined by JDK-8173970 but not backported to JDK23 yet.

All related JTREG tests passed
