These tests were added to the Skipped list on Mac, but probably just should have been given expected failing results. I am going to add failing expected results for Windows.

This is probably related to https://bugs.webkit.org/show_bug.cgi?id=85409

Added the Windows expected (failing?) results in http://trac.webkit.org/changeset/119120

[Jean-Yves Avenard [:jya]]

The tests are failing because it incorrectly assumes that if testing for codecs support in one container assumes that it will also be supported in another container.

like:
```
 if (v.canPlayType('video/mp4; codecs="avc1.42E01E, mp4a.40.2"') == "probably") {
  assert_equals(
   v.canPlayType('video/mp4; codecs="avc1.42E01E, mp4a.40.2"'),
   v.canPlayType('video/ogg; codecs="avc1.42E01E"'),
   "ability to play two codecs implies the ability to play one");
 }
```

that avc1 and mp4a is supported in an mp4 doesn't imply that video/ogg is supported.

WebKit on Mac or WPE doesn't support the ogg container.
