Generated code incorrect for typedef'd function pointers

[ThadHouse]

In a lot of Windows API's, when a callback is passed to a function, usually the function pointer itself is declared as a function type, with a typedef into a function pointer. ClangSharp doesn't seem to like this, and generates a double function pointer instead, which is incorrect.

#pragma once

typedef
int
(__cdecl Callback)(
    int Input
);

typedef Callback *CallbackHandler;


typedef struct Thing {
    CallbackHandler CB;
} Thing;

This code should generate

namespace TestNS
{
    public unsafe partial struct Thing
    {
        [NativeTypeName("CallbackHandler")]
        public delegate* unmanaged[Cdecl]<int, int> CB;
    }
}

But insteads generates as

namespace TestNS
{
    public unsafe partial struct Thing
    {
        [NativeTypeName("CallbackHandler")]
        public delegate* unmanaged[Cdecl]<int, int>* CB;
    }
}

Which is incorrect because of the extra indirection on CB.
