RFR 8071424: JCK test api/java_net/Socket/descriptions.html#Bind crashes on Windows

[Chris Hegarty]

This is a fix for a minor oversight when refactoring the initializing of 
Inet[4|6]Address IDs, used in many places in the networking native code.

It would appear that there is an initInetAddressIDs() call missing from 
the Windows Dual Stacks Socket implementation, 
Java_java_net_DualStackPlainSocketImpl_initIDs.  An existing test has 
been amended to cover this.
