[DocsUI, Search]: Enable listing of archives.

Adds a code that detects if the listed document is an archive. If so, it
calls local archive provider to create a loader that allows us to access
the archive content. Saves the ContentProviderClient in document result,
so that it can be closed when document result is closed.
