[QUIC] IPv6 addresses don't work on Linux

[rzikm]

#66794 replaced SOCKADDR_INET structure serialization by existing code in SocketAddress class, which uses platform-dependent values for the OS-level IPv6 address family enum. However, current version of MsQuic used by runtime uses Windows values on all platforms.

The IPv6 functionality on Linux will be fixed once we upgrade to MsQuic 2.0 (tracked by #64554), since that release uses the platform-specific enum values.

I'm still getting:
System.Net.Quic.QuicException : Failed to connect to peer. Error Code: INVALID_PARAMETER
With newest and greatest msquic, so the msquic update is not enough to solve this issue.

I'll keep the tests disabled. @rzikm could you give it a look after I put up a PR for the update?

The problem is the QUIC_ADDRESS_FAMILY we pass into the QuicConnectionStart function, which still uses the windows value for IPv6.

We can either plug UNSPEC temporarily. The value is not used anyway because we set the REMOTE_ADDRESS connection parameter separately before calling QuicConnectionStart. Or we can just wait for #67377.

#67377 was merged, tests pass. Closing
