Set global current_test_metadata for each test run so other test frameworks can choose to access fields for the current test.
This avoids having to pass _metadata down through functions so that code defined other functions can still use fields in _metadata. Test functions t->fn() are executed in series, so during the runtime of the test function, the function can count on current_test_metadata accurately being the metadata for the running test.
