Remove code path that passes a file handle to the renderer

Since the code now does range request without any caching
the code path for passing file handle is not used any more.

Changes:
1. Remove response_data_file in webkit_glue::ResourceResponseHead
2. Remove response_data_file in net::ResourceInfo
3. Remove code that passes file handle using IPC
4. Remove code that passes file hadnle from network layer to ResourceDispatcherHost
5. Remove MediaResourceHandler
6. Remove code in disk_cache that expose the file handle
7. Remove ChromeURLRequestContext::CreateOffTheRecordForMedia() so no more OTR request context for media, in OTR mode simply memory cache is used
8. Reset cache size for media cache to default
