Adding a global accessibility action to open quick settings.

1. Added APIs for opening the quick settings to the StatusBarManagerService
   and the local StatausBarManager. The new APIs are protected by the old
   EXPAND_STATUS_BAR permission.
   Renamed the expand* and collapse* non-public APIs that are expanding
   the notifications to expandNotifications* collapseNotifications* to
   better convey what they do given that this change adds
   expandQuickSettings* and collapseQuickSettings*.
   Added a global action to the accessibility layer to expand the quick
   settings which is calling into the new status bar manager APIs.
