[jdk11u] RFR: 8326643: JDK server does not send a dummy change_cipher_spec record after HelloRetryRequest message

Basically clean backport of [JDK-8326643](https://bugs.openjdk.org/browse/JDK-8326643). Only Copyright year update didn't apply cleanly. Added test adaptation from [JDK-8255867](https://bugs.openjdk.org/browse/JDK-8255867) (see 2nd commit).
