jmx-dev RFR: 8274398: Suppress more warnings on non-serializable non-transient instance fields in management libs [v2]

[Joe Darcy]

> Follow-up change to JDK-8232442, augmentations to javac's Xlint:serial checking are out for review (#5709) and various management libraries would need some changes to pass under the expanded checks.
> 
> The changes are to suppress warnings where non-transient fields in serializable types are not declared with a type statically known to be serializable. That isn't necessarily a correctness issues, but it does merit further scrutiny.
> 
> I'll run a script to update copyright years before a push.
