Avoid duplicate BuiltIn variables for ray tracing matrices (fix #2921)
Fixes an issue where invalid SPIR-V was generated when gl_ObjectToWorldEXT and gl_ObjectToWorld3x4EXT, or gl_WorldToObjectEXT and gl_WorldToObject3x4EXT, were used in the same shader. The SPIR-V specification requires that there be at most one OpVariable decorated with a given BuiltIn value.
