RFR: 8280054: BadSerializationTest and DragGestureEvent/DragGestureRecognizer constructors

Tue Jan 18 21:02:44 UTC 2022

Please consider this enhancement to `test/jdk/java/awt/dnd/BadSerializationTest/BadSerializationTest.java`, which simplifies the process of manually generating serialized test data by using reflection to generate invalid instances of `DragGestureEvent` and `DragGestureRecognizer`, instead of relying on patching the constructors of those classes to disable validation checks.

This cleanup was proposed in the review for a possible fix for [JDK-8277817](https://bugs.openjdk.java.net/browse/JDK-8277817): https://git.openjdk.java.net/jdk/pull/6603#issuecomment-997054470
