glsl: Move type_contains_sampler() into glsl_type for later reuse.

The new location, as a member function of glsl_type, is more
consistent with queries like is_sampler(), is_boolean(), is_float(),
etc.  Placing the function inside glsl_type also makes it available to
any code that uses glsl_types.
