Security related app-ops should be set with AppOpsManager#setUidMode
instead of AppOpsManager#setMode.
Test: manual - toggle All Files Access for a test app, reboot device and
observe in /data/system/appops.xml that the mode was for UID instead of
package
Test: ensure that the right state is reflected in the relevant Settings
activities

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'
