fix: Undefine Windows macros to prevent conflicts with protobuf generated code

- Added preprocessor directives to undefine the DWORD and ERROR macros on Windows, ensuring compatibility with protobuf generated code in imgui_test_harness_service.h and gui_automation_client.h.
- This change prevents potential compilation issues when using gRPC and protobuf in a Windows environment.
