Fix OMShell-terminal on Windows and add a CMake Windows job. (#9725)

  - There is now a PR CI job that can build OpenModelica with CMake on
    Windows. This is disabled by default and can be enabled by setting the
    label (on the PR):
    `CI/CMake/Enable/macOS`

  - OMShell-terminal: use `simulation/socket.h` from our runtime code
    instead of directly including `sys/socket.h`. OMShell-terminal can
    now be compiled on Windows and seems to work just fine.
