Remove uses of async_minitest and multitests. Removed two files that were checking dynamic behavior that no longer exists (compile-time errors reported at runtime). Rewrote and/or added to enum_const_test.dart and _deferred_in_isoltae_test.dart. Otherwise mainly removing multitest `//# ok:...` comments, or `//# 01: ...error...` that only existed because the test failed in dart2js, along with anything else that tried to special-case dart2js (which no longer supports isolates at all). Some sporadic general clean-up like removing library names.
