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

[Sergey Bylokhov]

Please review the application of the `@Serial` annotation ([JDK-8202385](https://bugs.openjdk.org/browse/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 https://github.com/openjdk/jdk/pull/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 =`
