New user switcher dialog
This dialog will eventually replace the UserDetailView. Right now, it
uses the same adapter to display the content (which is not necessarily
bad).
To enable:
1. `adb shell setprop persist.systemui.flag_new_user_switcher 1`
2. `adb shell am crash com.android.systemui`
Missing:
* Red lines (including landscape size).
* Bring user circles up to spec (once it's finalized).
* Launch animations (to and from dialog).
