ImportC with typedef anonymous enums

[Chance Snow]

I am also experiencing this issue with the following C enum:

```c
// A list of all possible value types in WebAssembly.
typedef enum {
   // Signed 32 bit integer.
   I32,
   // Signed 64 bit integer.
   I64,
   // Floating point 32 bit integer.
   F32,
   // Floating point 64 bit integer.
   F64,
   // A 128 bit number.
   V128,
   // A reference to a Wasm function.
   FuncRef,
   // A reference to opaque data in the Wasm instance.
   ExternRef,
} ExtismValType;
```

Not sure why, either, but this workaround also works for me.
