Subject: FolderPanel: prevents scanning directory tree recursively

KFileItemListView contents are periodically scanned by KFileItemModelRolesUpdater.
It uses then KDirectoryContentsCounter to scan directories to determine their size possibly recursively.

Introduce a scanDirectories setting to disable directory scanning by KFileItemModelRolesUpdater.

BUG: 426617
