Add ActivityOption to remove keyguard when an activity is launched.

Replaced ActivityOption#dismissKeyguardIfInsecure by
ActivityOption#dismissKeyguard, with which the server doesn't check if
the keyguard is insecure again. The caller has to make sure if the
keygaurd can be dismissed without additional authentication.
