RFR: 8316804: Gracefully handle the case where --release is not specified last [v2]

[Christian Stein]

> Please review this change for the `jar` tool to gracefully handle the case where `--release` is not specified as the last arguments.
> 
> Prior to this commit, operation modes `-d --describe-module` and `--validate` expected to read the optional `--release` option as a file argument: `jar -d -f a.jar --release 9`
> By adding a hidden GNU-style `--release` option, processing the optional arguments before in those two operation modes, the position is now no longer required to trail behind the `-f --file` option: `jar -d --release 9 -f a.jar`
