Add keyguard shortcut for opening QS user panel

 - Introduce config_keyguard_user_switch_opens_qs_details. When set to
   true, the user icon that appears when config_keyguardUserSwitcher=true
   will open the "user" QS panel instead of taking over the keyguard

 - Add user icon positioning calculation to
   KeyguardClockPositionAlgorithm

 - Add option to QS DetailAdapter for turning off the circular reveal
   animation

 - Add callback to QS DetailAdapter for when "Done" button is pressed

 - Fix typo: showDetailDapater -> showDetailAdapter
