fix #14795: FP unusedStructMember when type is a template parameter

I wonder why the TODO in boost.cpp is not resolved.

This one?

cppcheck/test/cfg/boost.cpp

Line 235 in 8c14fc7

struct is_dataset<fibonacci_dataset> : boost::mpl::true_ {};

It's a different case for specializations because the tokens are pasted together: "is_dataset < fibonacci_dataset >". I'll add a new ticket.

I actually misread that code, the template specialization cannot use the struct member. The type (or an object thereof) is used in the BOOST_DATA_TEST_CASE macro though, so unusedStructMember should bail out on that.

would it make sense to add an example where the const keyword is used also?
