There was a time when Android didn't depend on ui/events, only on
ui/events/events_base. (https://codereview.chromium.org/241213002)

It looks like that's no longer the case, which is a shame. Unless we have a good
reason to, we shouldn't be adding new cases where Android depends on ui/events.
Do we have a good reason to do so here?

We actually need this for motion_event_android.h which we had to add to
ui/events when we were isolating the input files needed from content.

Do you think there is a different target that would be more suitable for this
file?
