Revert of Added multi-finger gestures to touch_exploration_controller

Revert of Added multi-finger gestures to touch_exploration_controller (https://codereview.chromium.org/429633002/)

Reason for revert:
tree-closer ui_unittests failing on Linux Chromium OS ASan LSan Tests (3)
test TouchExplorationTest.AllFingerPermutations
failing since
http://build.chromium.org/p/chromium.memory/builders/Linux%20Chromium%20OS%20ASan%20LSan%20Tests%20%283%29/builds/2708

I don't think the failing test itself is generating output, but
there are some LOG(INFO)s that have been snuck through
with the VLOG(0) trick which might help diagnose.

Original issue's description:
