Vlad Zahorodnii 88829de9dd wayland: Refactor creation of input panel clients
This change introduces a shell integration class for input panel
surfaces. This effectively breaks the direct dependency between our
virtual keyboard component in kwin and the input_panel protocol,
which means that an input method server could use the layer-shell
protocol instead of the input_panel protocol.
