Revert of Add mechanism to auto mount file systems in response to a URL request. (https://codereview.chromium.org/195923002/)

Reason for revert:
Best guess that this broke
SyncFileSystemApiTest.WriteFileThenGetUsage
SyncFileSystemApiTest.GetFileStatuses
MediaGalleriesPlatformAppBrowserTest.MediaGalleriesCopyTo
on XP Tests(1).

Original issue's description:
> Add mechanism to auto mount file systems in response to a URL request.
