"Free" a verifier previously returned from
rustls_client_cert_verifier_optional_new. Since rustls_client_cert_verifier_optional
is actually an atomically reference-counted pointer, extant server_configs may still
hold an internal reference to the Rust object. However, C code must
consider this pointer unusable after "free"ing it.
Calling with NULL is fine. Must not be called twice with the same value.
