Enhance argument handling in nt_6x_process_create_impl by adding quotation marks around paths

- Updated the process creation logic to include double quotation marks around the image path and process parameters when appending to argv0.
- Improved clarity in the handling of DOS and NT paths by ensuring proper formatting during argument construction.
