Clarify InputMethodSettings doesn't require ImfLock

With my previous CL [1], all the internal fields InputMethodSettings
do not need to be guared with ImfLock.

Thus we can safely remove "Locked" suffix from its methods.

Note that the returned values are still subject to change if other
threads are updating relevant SecureSettings, but it's not a new
problem.
