[tint][ast] Fix DirectVariableAccess with uncalled function ptr params

If a function has no calls, and in turn calls another function with a function-address-space pointer parameter, then we could incorrectly attempt to create a parameter with a pointer-to-pointer type.
The code was missing an `UnwrapPtrOrRef` - this wasn't noticed as most originating variables are `ref` types, and `CreateASTTypeFor()` will construct the storage type for a `ref` type.
