Convert Swarm System to gRPC and break up hosted service endpoints

[Cyberboss]

🆑 Configuration
The new configuration version is 6.0.0. There have been significant breaking changes that affect all upgrading users so read carefully.
BREAKING: Added Session:BridgePort which is the port the game uses to talk to TGS.
Added HostingSpecification objects. These have two keys IPAddress and Port which define an IP endpoint the server listens on. All HostingSpecifcations can use the same port as others in TGS (excluding game servers) unless explicitly specified otherwise.
BREAKING: Replaced General:ApiPort with General:ApiEndPoints HostingSpecifcation array.
BREAKING: Replaced General:PrometheusPort with General:MetricEndPoints HostingSpecifcation array.
BREAKING: Swarm configuration now requires a Swarm:EndPoints HostingSpecifcation array. The ports in these specs CANNOT overlap with any other ports in use by TGS.

🆑
BREAKING: TGS now requires the ASP.NET 10 runtime.
Health, metrics, and swarm endpoints are no longer accessible through the HTTP API unless configured otherwise.
The bridge request endpoint is now exclusively only available via localhost.
Removed undocumented IIS hosting support.
Added configuration validation system.
