XPC crashes while using .net7 and/or .net8

XPC Service does not work on .net7/8 and crashes in runtime with an NSXPCDecoder exception
The same code works fine when targeting .net framework 4.7.2

### Steps to Reproduce

1. Build and run the attached sample code. The repro code provides a bare minimum skeleton for running an XPC service using .net7 or .net8
2. To properly sign the project you might need to make some tweaks, since signing is broken for xpc (see the readme file with instructions)
3. Run the project
4. The exception will be thrown and available in the Console app

### Expected Behavior
The XPC Service should receive a Ping call from the main app

### Actual Behavior
The XPC Service crashes with a runtime exception

```
connection from pid 458 on anonymousListener or serviceListener: Exception caught during decoding of received selector ping, dropping incoming message.
Exception: received a message or reply block that is not in the interface of the remote object (ping), dropping.

### Example Project

[XpcDotNet.zip](https://github.com/xamarin/xamarin-macios/files/11423624/XpcDotNet.zip)

Start with the attached XpcDotNet.zip sample and its README, including the signing instructions, then run the reproduction on .NET 7 or .NET 8 and inspect the Console output for the NSXPCDecoder exception. Compare the behavior with the .NET Framework 4.7.2 target; done means the XPC service receives the app's Ping call without crashing.
