Disallow using combined textures and samplers in shaders

This patch adds a validation to disallow declaraing combined textures
and samplers in shaders.

SPVC doesn't provide a way to extract the information of combined
textures and samplers from shaders, so currently we cannot add the
related validation when we use SPVC.
