This commit adds fields to the ClientHelloInfo and ConnectionState
structures to represent hello retry request state information.
ClientHelloInfo gains a new HelloRetryRequest bool field that indicates
if the client hello was sent in response to a TLS 1.3 hello retry
request message previously emitted by the server.
ConnectionState gains a new HelloRetryRequest bool field that indicates
(depending on the connection role) whether the client received a TLS 1.3
hello retry request message from the server, or whether the server sent
such a message to a client.
Fixes#74425
