[Easy Unlock] When hardlocking, show a different icon on user

[Easy Unlock] When hardlocking, show a different icon on user

The previous behaviour was to hide it.

Also, update some icon resources.

Note: this does not yet work well with easy signin.

LGTM

Do we want to change UserSessionManager::UpdateEasyUnlockKeys to remove all keys
when hard lock is on?

No, I don't think we do. I think the hardlock should be disabled when the user
logs in (I had forgotten to upload the part that does this)

xiyuan, can you have another look at
chrome/browser/chromeos/login/session/user_session_manager.cc (I did not have
this in the reviewed patchset)
