skin engine: Reduce scope of internal wps_data struct

A bunch of public API calls take a wps_data struct argument,
but that's an internal type that doesn't have a direct getter.
Instead the skin engine provides a gui_wps struct as a way
to refer to a particular skin instance. Use that instead of
wps_data in the public API.
