Enum to disable member creation for inherited classes or interfaces

[ChaseFlorell]

Proposal: add a new inheritanceGeneration parameter to the GenerateAutomaticInterfaceAttribute so that we can turn off the unnecessary inheritance.

The rationale comes from all of my classes that implement IDisposable, and that I really don't need the Dispose() method defined in my custom interface.. and if I do, I'll do it myself public partial interface IMyClass : IDisposable;

[Flags]
public enum InheritanceGeneration
{
    AllowAll = 0, // default - prevents breaking changes
    DisableInterfaces = 1 << 0,
    DisableConcretions = 1 << 1,
    DisableAll = DisableInterfaces | DisableConcretions
}

Given a setup as follows

public class SomeBase
{
    public void SomeMethod(){}
}

[GenerateAutomaticInterface(allowInheritanceGeneration = InheritanceGeneration.DisableAll)]
public sealed class MyClass : SomeBase, IDisposable
{
    public void MySpecialMethod(){}
}

the automatic interface would be akin to

public interface IMyClass
{
    void MySpecialMethod();
}

note: naming is up for debate, its the concept that I'm advocating for.
