Experimental QUIC channel (.NET 9-only)

[yallie]

Added sketch channel based on QUIC network protocol (requires .NET 9.0).
QUIC is a fast reliable UDP-based protocol developed by Google as a foundation for HTTP/3.
It includes built-in TLS 1.3 layer and solves a few TCP performance issues.

The project is not included in the solution, currently for testing only.
Doesn't support anything but localhost connections.
The speed is roughly the same as websockets based on HttpListener:

The unit tests are not included, but they are trivial to add, i.e.:

using CoreRemoting.Channels;
using CoreRemoting.Channels.Quic;
namespace CoreRemoting.Tests;

public class RpcTests_Quic : RpcTests
{
    protected override IServerChannel ServerChannel => new QuicServerChannel();

    protected override IClientChannel ClientChannel => new QuicClientChannel();

    public RpcTests_Quic(ServerFixture fixture, ITestOutputHelper helper) : base(fixture, helper)
    {
    }
}

Very interesting. It can't hurt to look into future standards early on.
