Filippo Valsorda 106db71f37 crypto/tls: implement TLS 1.3 client authentication
Note that the SignatureSchemes passed to GetClientCertificate in TLS 1.2
are now filtered by the requested certificate type. This feels like an
improvement anyway, and the full list can be surfaced as well when
support for signature_algorithms_cert is added, which actually matches
the semantics of the CertificateRequest signature_algorithms in TLS 1.2.

Also, note a subtle behavior change in server side resumption: if a
certificate is requested but not required, and the resumed session did
not include one, it used not to invoke VerifyPeerCertificate. However,
if the resumed session did include a certificate, it would. (If a
certificate was required but not in the session, the session is rejected
in checkForResumption.) This inconsistency could be unexpected, even
dangerous, so now VerifyPeerCertificate is always invoked. Still not
consistent with the client behavior, which does not ever invoke
VerifyPeerCertificate on resumption, but it felt too surprising to
entirely change either.

Updates #9671
