Robot support for all phys clicks in Touch FW test

This patch adds Robot support for all the remaining physical click tests
in the touch fw test.  As the physical click gesture already exists,
this was just a matter of updating the robot wrapper to accept three and
four finger gestures and perform them on the pad.

BUG=chromium:325477
TEST=manual testing by running the FW test on a Lumpy
