LibWeb: Fetch source file when HTMLTrackElement src attribute changes

Browse source 
This commit begins to implement the track processing model. When the
`src` attribute is updated, we now fetch the given source file.
Currently, we always fire an `error` event once fetching is completed,
as we don't support processing the fetched data.
