8277983: Remove unused fields from sun.net.www.protocol.jar.JarURLConnection

[cost0much]

Clean backport. Enhancement that doesn't make any logic changes; I'd like to backport the bug fix JDK-6956385 but it doesn't apply cleanly because of this change, so backporting this first.

/approval request Enhancement change from JDK19 and already in JDK21. I want to backport bug fix JDK-6956385 but it doesn't apply cleanly due to this change. Applies cleanly and passes tier1 tests. Risk is low given in JDK21 and no change to logic.
