When clearing cache, also clear AVFoundation cache.

Source/WebCore:

Use AVAssetCache at a specified location on disk for all AVURLAssets. This AVAssetCache
can then be used to manage the cache storage used by AVFoundation. It is used to query the
contents of the cache in originsInMediaCache() and to clear the cache completely or partially in
clearMediaCache() and clearMediaCacheForOrigins().

Use SecurityOrigin instead of the less formal site String to represent origins in the cache.
