[displayService] Query harmaService for file handlers

Harma is the only service that knows which file types are supported by
the installed engine. With this patch harma is queried for the supported
file handlers.

Note. We cache the result and is valid for the lifetime of the
displayService. To change this a signal could be added to harma to
notify the users of a changed file handler support
