Now that we have a full implementation of the logic to check certificate compatibility, we can let applications just list multiple chains in Certificates (for example, an RSA and an ECDSA one) and choose the most appropriate automatically. NameToCertificate only maps each name to one chain, so simply deprecate it, and while at it simplify its implementation by not stripping trailing dots from the SNI (which is specified not to have any, see RFC 6066, Section 3) and by not supporting multi-level wildcards, which are not a thing in the WebPKI (and in crypto/x509). The performance of SupportsCertificate without Leaf is poor, but doesn't affect current users. For now document that, and address it properly in the next cycle. See #35504. While cleaning up the Certificates/GetCertificate/GetConfigForClient behavior, also support leaving Certificates/GetCertificate nil if GetConfigForClient is set, and send unrecognized_name when there are no available certificates.
