build: package and invoke install.cmd instead of install.ps1

The Windows ZIP now ships install.cmd, rewritten to CRLF by
configure_file so the package is right on any build host. The CMake
install target runs it through "cmd /d /c call", and install.cmd
replaces install.ps1 in the version input paths.
