RFR: 8312072: Deprecate for removal the -Xnoagent option [v2]

[Jaikiran Pai]

> Can I please get a review of this change which proposes to deprecate `-Xnoagent` option of the `java` command? This addresses https://bugs.openjdk.org/browse/JDK-8312072.
> 
> As noted in the JBS issue, this option currently is a no-op and provides no functionality. The commit in this PR logs a deprecation warning if this option is used when launching `java`.
> 
> Additionally, this PR also cleans up one such usage that I found in the JDK code.
> 
> `tier1`, `tier2` and `tier3` tests passed with this change. A CSR has been proposed for this deprecation https://bugs.openjdk.org/browse/JDK-8312073.
