qga: gspawn() console helper to Windows guest agent msi build

This helper, gspawn-win64-helper-console.exe for 64-bit and
gspawn-win32-helper-console.exe for 32-bit environment,
is needed for gspawn() mingw implementation, used by guest-exec command.

Without these files guest-exec command on Windows will not
work with "file not found" diagnostic message.
