windows/mkwinsyscall: use syscall.SyscallN instead of syscall.Syscall{6,9,12,15}

Browse Source 
Replace syscall.Syscall6, Syscall9, Syscall12, and Syscall15 with
syscall.SyscallN for Go 1.18+. This simplifies system calls by allowing
the exact number of arguments needed, eliminating zero padding and
reducing potential errors.

Updated TestSyscallXGeneration to TestSyscallNGeneration to verify
correct SyscallN generation for different argument counts.
