HTTP/3: UseHttps configuration

[JamesNK]

Ensure that we set any options configured with UseHttps with HTTP/3. Some values might not be supported by QUIC.

[Tratcher]

Note the UseHttps overloads that take async callbacks probably won't work at all. Make sure they fail with reasonable errors.

The synchronous SNI callback is supposed to work. dotnet/runtime#55468

HttpsConnectionAdapterOptions based UseHttps:

• X509Certificate2? ServerCertificate
• SslProtocols SslProtocols (N/A, TLS 1.3 is required)
• Func<ConnectionContext, string?, X509Certificate2?>? ServerCertificateSelector - Enable ServerCertificateSelector for HTTP/3  #35243, no ConnectionContext.
• ClientCertificateMode ClientCertificateMode Http/3 client certificates #35308
• Func<X509Certificate2, X509Chain?, SslPolicyErrors, bool>? ClientCertificateValidation Http/3 client certificates #35308
• bool CheckCertificateRevocation Http/3 client certificates #35308
• TimeSpan HandshakeTimeout - HandshakeIdleTimeoutMs
• Action<ConnectionContext, SslServerAuthenticationOptions>? OnAuthenticate - Blocked, no sync per connection SslServerAuthenticationOptions callback, no ConnectionContext.

ServerOptionsSelectionCallback based UseHttps:

• UseHttps(this ListenOptions listenOptions, ServerOptionsSelectionCallback serverOptionsSelectionCallback, object state, TimeSpan handshakeTimeout) - Blocked, no async per connection SslServerAuthenticationOptions callback.

TlsHandshakeCallbackOptions's based UseHttps: - Blocked, no async per connection SslServerAuthenticationOptions callback, no ConnectionContext

All of the unblocked items have been addressed for .NET 6. Moving to .NET 7.

We need to ask for runtime APIs for the rest of these.

[JamesNK]

@Tratcher How many of the remaining options does runtime implementing HTTP/3: QuicConnectionListener supports ServerOptionsSelectionCallback unblock? Are there other changes required from their side or is this it?

[JamesNK]

There is also dotnet/runtime#55378 but it seems pretty minor.

[Tratcher]

Waiting on dotnet/runtime#67560
