8274396: Suppress more warnings on non-serializable non-transient instance fields in client libs

[jddarcy]

Follow-up changes to JDK-8231334. , augmentations to javac's Xlint:serial checking are out for review (#5709) and various client 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 the copyright year before pushing.
