Add settings UI for MANAGE_EXTERNAL_STORAGE

Adds a Special App Access setting for the app-op OP_MANAGE_EXTERNAL_STORAGE. All apps requesting the corresponding permission will be displayed in the settings page. Toggling the preference switch for an app will grant/revoke the app-op. All of the external references to the permission, app-op and their corresponding activities and logic use the name "Manage External Storage". All of the external displays and strings use the name "All files access" Test: * Install app with uses-permission MANAGE_EXTERNAL_STORAGE * Observe it appearing the All files access page * Toggle the switch and observe the change in 'adb shell dumpsys appops' Bug: 146425146 Change-Id: If5c9c5daa3616a3310c090283acfda933bf9df26
