Rename media_queries::MediaQueryList to MediaList

<!-- Please describe your changes on the following line: -->
`MediaList` is the name of the interface for "collection of media queries" used in [CSSOM spec](https://drafts.csswg.org/cssom/#the-medialist-interface), `MediaQueryList` happens to mean something different in [CSSOM View spec](https://drafts.csswg.org/cssom-view/#the-mediaquerylist-interface), which also leads to naming conflict in dom code. So I think it's better renaming it to `MediaList`.
