Copy chromeos_input_method* from libcros as-is.

We'll be modifying these files so we can use the code from Chrome
without going through libcros. Before doing that, we check in the
code as-is, so we can track diffs.

% cp ~/chromeos/src/platform/cros/chromeos_input_method.cc ibus_controller.cc
% cp ~/chromeos/src/platform/cros/chromeos_input_method.h ibus_controller.h
% cp ~/chromeos/src/platform/cros/chromeos_input_method_unittest.cc ibus_controller_unittest.cc
