[SignalR functions bindings] Self-implemented MessagePack hub protocol

[Y-Sindo]

As Microsoft.AspNetCore.SignalR.Protocols.MessagePack 1.x relies on an unsecure MessagePack version 1.x, and we cannot update Microsoft.AspNetCore.SignalR.Protocols.MessagePack to 2.x as we have to support .NET Standard 2.0 framework, we implement the required functionalities of Microsoft.AspNetCore.SignalR.Protocols.MessagePack with MessagePack 2.0

• Copied MessagePackHubProtocol files from https://github.com/dotnet/aspnetcore/blob/0825def633c99d9fdd74e47e69bcde3935a5fe74/
• Self-implemented MessagePack Hub Protocol
• Fix security code alert
• Cleanup dependencies

This pull request includes several updates and improvements to the Microsoft.Azure.WebJobs.Extensions.SignalRService package, including dependency updates, breaking changes, and new internal implementations for MessagePack protocol support.

Dependency updates:

• Updated MessagePack to version 2.5.192 and Microsoft.Azure.SignalR packages to version 1.29.0 in eng/Packages.Data.props and CHANGELOG.md files. [1] [2]

Breaking changes:

• Removed .NET 6.0 support from Microsoft.Azure.WebJobs.Extensions.SignalRService.csproj. [1] [2]

New internal implementations for MessagePack protocol:

• Added BinaryMessageFormatter, DefaultMessagePackHubProtocolWorker, MessagePackHubProtocol, and MessagePackHubProtocolWorker classes to support MessagePack serialization and deserialization. [1] [2] [3] [4]

Code improvements:

• Added JTokenWrapperMessagePackFormatter to JTokenWrapper class for MessagePack serialization support. [1] [2]
