8253965: Delete the outdated java.awt.PeerFixer class

[mrserb]

This bug is extracted from the JDK-8251123. Instead of specifying this old/unused class, I suggest to delete it.

This is the comment added to this class in JDK 1.1.1:

==============================
/*

• In JDK 1.1.1, the pkg private class java.awt.PeerFixer was moved to
• become an inner class of ScrollPane, which broke serialization
• for ScrollPane objects using JDK 1.1.
• Instead of moving it back out here, which would break all JDK 1.1.x
• releases, we keep PeerFixer in both places. Because of the scoping rules,
• the PeerFixer that is used in ScrollPane will be the one that is the
• inner class. This pkg private PeerFixer class below will only be used
• if the Java 2 platform is used to deserialize ScrollPane objects that were serialized
• using JDK1.1
  */
