RFR: 8345176: Add tests to verify java.net.Socket constructors close the socket on failure [v4]

[Volkan Yazıcı]

> [8343791](https://bugs.openjdk.org/browse/JDK-8343791) (addressed by #22160) stresses that `Socket::connect()` failures should be handled such that the resultant state of the `Socket` and its underlying `SocketImpl` should match. In a similar fashion, `Socket::new` (which is using `bind()` and `connect()` under the hood) failures should not leave behind an open `SocketImpl` either. This change set, addressing [8345176](https://bugs.openjdk.org/browse/JDK-8345176), adds `CtorFailTest` verifying this behavior.
