8246039: SSLSocket HandshakeCompletedListeners are run on virtual threads

Previously each `SSLSocket.addHandshakeCompletedListener(HandshakeCompletedListener)`
resulted in a new OS thread for each handshake which causes spikes in
resource utilization and bottlenecks in high throughput systems.

Virtual threads should reduce the overhead while preserving behavior to
the extent possible.
