Add UseCounters for name attribute matching of <map> and <input type=radio>

https://github.com/whatwg/html/issues/1666
We'd like to know if Unicode caseless matching is really necessary for
them. This CL adds the following counters of cases where:
 - Exact codepoint matching is enough
 - ASCII-caseless matching is enough
 - Otherwise
for each of <map> and <input type=radio>.
