8374838: Apply java.io.Serial annotations in java.management.*

[mrserb]

Please review the application of the @Serial annotation (JDK-8202385) to types in the java.management.* modules. The goal is to enable stricter compile-time checking of serialization-related declarations.

The change is not small. I could split it, but I decided to do it as a single change since covering the module in one shot is easier than managing a bunch of separate PRs.

Example of a similar change #24891.

Note: this annotation can be applied to these methods and fields:

• private void writeObject(java.io.ObjectOutputStream stream) throws IOException
• private void readObject(java.io.ObjectInputStream stream) throws IOException, ClassNotFoundException
• private void readObjectNoData() throws ObjectStreamException
• ANY-ACCESS-MODIFIER Object writeReplace() throws ObjectStreamException
• ANY-ACCESS-MODIFIER Object readResolve() throws ObjectStreamException
• private static final ObjectStreamField[] serialPersistentFields
• private static final long serialVersionUID

Additional changes:

• Copyright years were updated
• Imports were not touched much (no sorting or cleanup); the new import was added in a reasonable place
• In several places static final long serialVersionUID = was changed to
  private static final long serialVersionUID =
