feat: bundle WinUSB driver files and libusb DLL in repo

Add installer/drivers/ with all Windows USB driver dependencies:
- kneron_winusb.inf (KL520/KL720 WinUSB driver)
- amd64/WdfCoInstaller01011.dll (WDF co-installer)
- amd64/winusbcoinstaller2.dll (WinUSB co-installer)
- libusb-1.0.dll (USB communication library)

Previously these files were sourced from external local_service_win/
directory which may not exist on build machines. Now all build
scripts (Makefile, build-installer.ps1) source from the repo.
