Update Xamarin.Messaging and renamed Xamarin paths

[mauroa]

Brings important changes around Xamarin deprecation and Mac paths:

• Updated Xamarin.Messaging to 18.0.136-g9e200fbc6d
• Added target before SayHello to set default Messaging context path values
• Adapted code to Messaging API changes
• IL merge BouncyCastle.Cryptography (new SSH.NET dependency)
• Updated from old Xamarin path to new maui path in test scripts
• Fixed CompileNativeCode to correctly resolve dotnet packs paths

@mauroa the SayHello task now fails with:
