Remove the extension init hook.

This is now never used. Instead, we rely on each renegotiation creating
a new handshake structure with fresh state. This simplifies things for
ECH.

(We probably could make an init hook work with ECH's two-ClientHello
scheme by either maintaining separate state per ClientHello or calling
init once for both ClientHellos. But the few uses of init were
removable, so this is easier.)
