[SmartLock] Delete hardlock icon tap callback

Now that Sign in with Smart Lock is deprecated there is no use for
hardlock. This CL deletes the EasyUnlock icon tap callback which is
supposed to trigger hardlock. Hardlock and the EasyUnlockIcon is doubly irrelevant since the SmartLockUIRevamp is also fully ramped up already. Follow up CLs will delete Hardlock UI, state management, and user prefs.

TEST=existing unittests test and manually tested smart lock with strongbad and pixel4a
