Add app compat flag to enable/disable scoped storage

Bug: 132649864
Test: * Sample app targetting R is not able to create test.pdf in
        DCIM (due to scoped storage restrictions)
      * `adb shell am compat disable SCOPED_STORAGE <pkg_name>` or go to
      Settings-> App Compatibility->(Select app)-> toggle SCOPED_STORAGE
      * Able to create test.pdf in DCIM (hence opt out of scoped storage)
