RFR: 8339918: Remove checks for outdated -t -tm -Xfuture -checksource -cs -noasyncgc options from the launcher

[Jaikiran Pai]

Can I please get a review for this change which cleans up the `java` launcher to remove checks/support for outdated options?

As noted in https://bugs.openjdk.org/browse/JDK-8339918, these 6 options have been outdated and unsupported for several releases now. 2 of them even throw an error currently. The change in this PR removes the code which had specific checks for these options and will now consider these options just like any other unknown option to the launcher.

tier1, tier2 and tier3 testing passed with these changes. Higher tier testing is in progress.

Would this change require a CSR?
