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
