Windows: discover newer SDK MSI tools

Enhance build_msi_x64.bat to enumerate installed Windows Kits 10 SDK bin directories matching 10.* and select the newest x86 path that contains the MSI tools.

Keep VC_DIR_PLATFORMSDK as the first override and preserve the existing fixed SDK fallback paths for older installations.

Require MsiInfo.exe during discovery as well as msitran.exe and msidb.exe so the selected SDK path supports the final MSI metadata step.
