[DO NOT MERGE] Enforce INTERACT_ACROSS_USERS_FULL permission for NotificationAccessDetails

When using EXTRA_USER_HANDLE, check for INTERACT_ACROSS_USERS_FULL permission on calling package.

Bug: 259385017
Test:
 1. Build a test app that creates and starts an intent to NOTIFICATION_LISTENER_DETAIL_SETTINGS while setting the intent extra  "android.intent.extra.user_handle" to UserHandle(secondaryUserId).
 2. Create and switch to a secondary user
Settings > System > Multiple users > Allow multiple users > Add user > Switch to New user
 3. Open Settings > Notifications > Device & app notifications and choose an app from the list (uses android.permission.BIND_NOTIFICATION_LISTENER_SERVICE). Enable Device & app notifications for selected app and disable all attributed permissions.
 4. Switch back to the Owner user.
 5. Get the userId of the secondary user: adb shell pm list users.
 6. Open the test app and enter the userId for the secondary user and the component name that uses android.permission.BIND_NOTIFICATION_LISTENER_SERVICE.
 8. In the settings window that open, enable all 4 sub-options.
 9. Switch to the secondary user and note that the all sub-options for the app are disabled.
