Rewrite WPT WebAudio tests to work on Chrome

Chrome times out on these tests because the test throws an exception
in a promise resolver. Rewrite the tests to use the promise_test
method which handles these.

Manually verified that Firefox still passes these tests, and that
Chrome fails them instead of timing out. TestExpectations updated
appropriately.
