This change significantly improves TLS handshaking latency and throughput for services that utilize multiple `SSLContext`. As an example, Apache Kafka running on JDK 17 with significant numbers of clients may see over 40% of CPU utilization due to `SessionTicketExtension$KeyState.cleanup(HandshakeContext)`.
