Fix SPV return type of rayQueryGetIntersectionInstanceShaderBindingTableRecordOffsetEXT (#2484)
Issue #2483 According to GLSL spec the prototype is: uint rayQueryGetIntersectionInstanceShaderBindingTableRecordOffsetEXT(rayQueryEXT q, bool committed); but that was incorrectly getting translated to SPIRV as an `int`, and this was causing SPIR-V validation errors when used. Added explicit testing for the return types of all the builtin functions in GL_EXT_ray_query
