packer: Install and use Microsoft provide OpenSSH

For the packer-built stemcells install OpenSSH as part of VM setup, not
WinRM because executing `Add-WindowsCapability` via WinRM does not
appear to be allowed. So instead move the installation of OpenSSH.Server
to the various IaaS pre-boot scrips which are not executed via WinRM.

The installations of OpenSSSH.Server happens as follows:
- Azure: add a `custom_script` parameter to packer config
- AWS: added to `setup_winrm.txt`
- GCP: add to `setup-winrm.ps1` and use `sysprep-specialize-script-ps1`
- vSphere: TODO
