Add support for templated tests
This adds support for templated tests and test methods via `TEMPLATE_TEST_CASE` and `TEMPLATE_TEST_CASE_METHOD` macros. These work mostly just like their regular counterparts*, but take an unlimited** number of types as their last arguments. * Unlike the plain `TEST_CASE*` macros, the `TEMPLATE*` variants require a tag string. ** In practice there is limit of about 300 types.
