  [iOS] Disable QuickLook thumbnails when using the Web Share API

Reviewed by Wenson Hsieh.

Display document icons rather than thumbnail previews when files are shared
using the Web Share API.

To achieve this behavior, provide a placeholder URL using a `UIActivityItemProvider`.

Note `-[UIActivityItemProvider item]` can also be leveraged to further defer
writing to files, beyond our existing logic to write files prior to handing off items to
the Share Sheet (using a `WorkQueue`). However, since `-[UIActivityItemProvider item]`
must return a non-nil value, and the file-writing path has multiple failure modes,
the existing file-writing logic is preserved.
