iioExplorer: Build attribute tree eagerly; query libiio in CliDetailsView.

Create all device/channel attribute items at connection time without
constructing IIOWidgets, so the tree is fully populated for search
immediately. Rewrite CliDetailsView to query libiio directly on a
background thread instead of reading from IIOWidget data strategies.
