Disable IdentityVerifier in SslStreamSecurityBindingElement

Hi,

WCF client doesn't provide a feature to disable or implement own IdentityVerifier in SslStreamSecurityBindingElement.

I have a task in which I implemented own certificate validator.
```
var authentication = clientBase.ClientCredentials.ServiceCertificate.Authentication;

authentication.CertificateValidationMode = X509CertificateValidationMode.Custom;
authentication.CustomCertificateValidator = validator;
```
There is a case when the validation passes successfully but I get an exception from IdentityVerifier.
For instance, domain name in a server certificate doesn't equal domain name of a client.
I run the client on localhost.

```
System.ServiceModel.Security.MessageSecurityException: Identity check failed for outgoing message. The expected DNS identity of the remote endpoint was '127.0.0.1' but the remote endpoint provided DNS claim 'anydomainname'. If this is a legitimate remote endpoint, you can fix the problem by explicitly specifying DNS identity 'anydomainname' as the Identity property of EndpointAddress when creating channel proxy.

```

On .net472 I can implement own IndentityVerifier and pass it to SslStreamSecurityBindingElement to ignore validation.
```
var sslStreamElement = bindingElements.Find();
sslStreamElement.IdentityVerifier = customIdentityVerifier;
```

But SslStreamSecurityBindingElement doesn't have IdentityVerifier property in your library on .net6.

Is there a way disable that validation?
