[filesapp] Use dedicated API to fetch ARC DocumentsProvider thumbnails
Add a special case for ARC DocumentsProvider URLs to the image loader to
fetch thumbnails using a dedicated fileManagerPrivate function. The
function checks document metadata for a thumbnail support flag, and, if
set, fetches the actual thumbnail via a mojo call to ARC.
If the document does not have a thumbnail, no thumbnail is rendered,
rather than falling back to download the original file and resizing it
into thumbnail.
Mojo struct Size was moved from video_common.mojom to gfx.mojom as it's
now used by the filesystem API as well.
