RFR: 8293667: Align jlink's --compress option with jmod's --compress option [v9]

[Ian Graves]

> This is an approach to adding a flag to jlink that will allow --compress to take the same types of arguments as jmod, thus bringing the two into alignment. This likely requires a CSR and a discussion on whether we should deprecate or simply remove the original numeric compression arguments.
