Creating GetTouchExplorationController() in RWC just for the test seems bad.
Also, this would need to be surrounded by ifdef(OS_CHROMEOS). To make this a bit
cleaner, I'd suggest creating a test class wrapping RWC and putting the method
there. Take a look at WindowEventDispatcherTestApi and how it's used as an
example. You can then put the tests class into a chromeos-specific folder or add
"_chromeos" suffix to the filename to make sure it's not compiled on other oses.

Also a nit (not specific to this change): I think it would be good to get rid of
CallTapTimerNowForTesting() and instead inject base::MockTimer into
TouchExplorationCOntroller and then operate the MockTimer.
