Add unified preview UI

ChooserContentPreviewUi applies various heuristic to determine if each
shared URI has a preview and, if any, displays a scrollable preview
list. Each preview item in the list is badge accroding ot its type: no
badge for images, a video-file badge for videos and a generic-file badge
for all others. All URIs without a previwe are groupped under a single
item at list end (+N files).

Collateral changes:
 * FileContentPreviewUi$FileInfo is moved into the package level;
 * ChooserContentPreviewUi$ImageMimeTypeClassifier internface is moved
   into the package level, renamted to MimeTypeClassifier and defines a
   new method, isVideoType();
 * ScrollableImagePreviewView is modified to support badges and the
   "+N" item;
 * A new class, UnfifiedContentPreviewUi is clonned from
   ImageContentPreviewUi class, and is reponsible for drawing the new
   unified preview ui, ImageContentPreviewUi is used only with the
   legacy image content preview.
