Subject: layer-shell: allow new values for keyboard-interactivity

Value is now an enum with a new value ("on-demand") that compositors can use to allow "normal" keyboard focus semantics regardless of the layer the client surface is on. An error is sent for invalid keyboard interactivity values. The old behavior is retained for clients using the previous version of the protocol.

Also adjusted the layer-shell example program to use the new keyboard interactivity options.
