Change explicit usage of each type of message loop in WaitableEventWatcher tests to instead loop through an array of message loop types.

This allows for easier-to-read code while including a platform that cannot run the tests on every kind of message loop. Specifically, iOS cannot run the UI loop for unit tests.

Un-exclude synchronization/waitable_event_watcher_unittest.cc on ios in base.gyp.
