\brief Returns the number of template args of a function decl representing a template specialization.
If the argument cursor cannot be converted into a template function declaration, -1 is returned.
For example, for the following declaration and specialization: template <typename T, int kInt, bool kBool> void foo() { ... }
template <> void foo<float, -7, true>();
The value 3 would be returned from this call.
