Mark most Hungarian tokenizer test cases as slow (#4883)

* Mark most Hungarian tokenizer test cases as slow

Mark most Hungarian tokenizer test cases as slow to reduce the runtime
of the test suite in ordinary usage:

* for normal tests: run default tests plus 10% of the detailed tests
* for slow tests: run all tests

* Rework to mark individual tests as slow
