<i18n dev> RFR: 8259522: Apply java.io.Serial annotations in java.desktop [v2]

[Sergey Bylokhov]

> Please review the application of @java.io.Serial annotation (JDK-8202385) to types in the desktop module to enable stricter compile-time checking of serialization-related declarations.
> 
> This annotation can be applied to these methods in the module:
> 
>     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
> 
> Notes:
>   - I have tried to update the comments for serialVersionUID as accurately as possible, but mostly based on the source code history and bugs in JBS where that field was added
>   - Some of the readObject/writeObject methods in the javax.swing package does not have a spec, because this package and some others are excluded from the serialization specification.
> 
> A similar fix was implemented for java.base module as well:
