8274793: Suppress warnings on non-serializable non-transient instance fields in sun.net

[jddarcy]

Augmentations to javac's Xlint:serial checking are out for review (#5709) and the sun.net classes in this PR 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.

The changes in the PR are consistent with similar changes made in JDK libraries under the umbrella issue JDK-8231641.
