/* Key exchanges allowing client certificate requests.
*
* Note: that's almost the same as MBEDTLS_KEY_EXCHANGE_WITH_CERT_ENABLED
* above, except RSA-PSK uses a server certificate but no client cert.
*
* Note: this difference is specific to TLS 1.2, as with TLS 1.3, things are
* more symmetrical: client certs and server certs are either both allowed
* (Ephemeral mode) or both disallowed (PSK and PKS-Ephemeral modes).
