This CL upstreams most device orientation tests to WPT.

- Moves device orientation tests from
  web_tests/device_orientation/,
  web_tests/http/tests/security/powerfuFeatureRestrictions/,
  to web_tests/external/wpt/orientation-event with some necessary
  updates to adapt to WPT test framework.
- Retains two page-visibility.html tests as which could not be
  automated in WPT at present and adds two similar manual tests
  there to keep test coverage sufficient.
- Leaves existing tests as is, further improvement (e.g. remove duplicate
  tests, use EventWatcher, etc.) will be arranged in a follow-up.
- Updates test paths in some profiles.
