Reviewed by Andread Kling.

MediaList is a CSSOM type and should not be used internally.
        
- Use new type MediaQuerySet internally to represent a collection of media queries.
- Create MediaList wrapper on-demand for CSSOM purposes only.
        
This moves us forward in separating CSSOM from the internal stylesheet implementation.
        
MediaQuerySet really belongs to a file of its own but that is not part of this patch.

    - Use OwnPtr<> for MediaQuery ownership.
    - Move the appropriate functions to MediaQuerySet.
    - Clean up a bit to make this more readable and better aligned to WebKit style.
