JDK-8253119 - Remove the legacy PlainSocketImpl and PlainDatagramSocketImpl implementation
Description
Legacy implementations of `java.net.SocketImpl` and `java.net.DatagramSocketImpl` have been removed from the JDK. The legacy implementation of `SocketImpl` has not been used by default since JDK 13, while the legacy implementation of `DatagramSocketImpl` has not been used by default since JDK 15. 
Support for system properties `jdk.net.usePlainSocketImpl` and `jdk.net.usePlainDatagramSocketImpl` used to select these implementations has also been removed. Setting these properties now has no effect.
