AppHost configuration to not attach debugger to a project

### Is your feature request related to a problem? Please describe the problem.

It would be useful to be able to configure a .NET project that you don't want the debugger attached when the app host is run with debugger.

I have a niche scenario where I explicitly don't want the debugger because the library has different behavior depending on whether the debugger is attached or not.

A more common ask for this is you don't want to debug into a particular app or be alerted by exceptions thrown in the app. There would also be performance benefits to not attaching the debugger to apps when not wanted.

### Describe the solution you'd like

An API in the app host to configure a .NET project not to be launched with the debugger attached.
