C#: calls bind to enum members of the same name (follow-up to #3795) #4245

Pre-flight checks

• I have checked the Troubleshooting section in the README

What happened?

#3795 is fixed for type references: base types and parameter types no longer resolve to enum
members. Calls still do. Invoking a delegate-typed field gets a calls edge to an enum member
that shares the field's name.

Steps to reproduce

`Eval.cs`:


namespace Demo
{
    public delegate float Curve(float t);
    public class Eval
    {
        public enum Kind { Linear, Delegate }
        public Kind Mode;
        public Curve Delegate;
        public float Evaluate(float t)
        {
            switch (Mode) { case Kind.Delegate: return Delegate != null ? Delegate(t) : t; default: return t; }
        }
    }
}


`graphify extract . --code-only`

Error output or graph output

### Actual


eval_demo_eval_evaluate --calls--> eval_demo_kind_delegate


`eval_demo_kind_delegate` is the enum member `Kind.Delegate`.

### Expected

No `calls` edge to `Kind.Delegate`. An enum member (or a property) can never be the target of a
call. `Delegate(t)` invokes the field; with no project method to point at, it gets no edge (or an
`unresolved_calls` entry).

Additional context

In a ~120-file Unity project, 5 calls still land on enum members on 0.9.80. The other shapes
are inj.Handles[i].Pause() landing on an enum member Pause, and
store.Vector2[idx] = new Vector2(...) (also Vector3, Quaternion) landing on enum members of
those names. Excluding enum members and properties from call-target lookup, as #3795 did for type
lookup, would cover all of them.
