Subject: ENH: Enable basic OpenVMS platform support

This adds the Modules/Platform/OpenVMS.cmake platform file for OpenVMS.
We just use Unix-like rules to work with the GNV compiler front-end.

A problem with process execution currently prevents CMake link scripts
from working, so we avoid using them.
