ChromeOS user_manager: move all KnownUser code to separate file.

Include components/user_manager/user_manager.h has become too heavy.
This CL moves all KnownUser stuff to a new known_user.{cc,h} so that
we do not need to include all user_manager if only known_user is needed.

BUG=462823
TEST=manual
