Use speed-profile with the cloud profile for apks loaded by other apps.

- Add `getOdexVisibility`, which returns the visibility of the odex file
  of an APK.
- Change `prepareAppProfile` to accept `userId` being `USER_NULL`. This
  is needed by the corresponding change in framework/base, which passes
  `USER_NULL` as `userId` to indicate that the current profile should
  remain unchanged.
