unexposed_t type when template parameters are omitted.

[deadlocklogic]

• cppast version: latest one
• parser: libclang_parser
• clang version: 13.0.0

Explanation of the error.

Input:

template <typename T>
class Test {
public:
    Test(const Test&) = delete;
};

The parameter's cpp_reference_type.referee()->kind() is giving unexposed_t.

Adding explicit template parameters solves the issue.

template <typename T>
class Test {
public:
    Test(const Test<T>&) = delete;
};

Possible bug? Or limitation?

This is a libclang limitation, unfortunately. I think it's related to #4.
