automation: transition to Windows Server 2022

Let's keep our Windows build environment modern by upgrading to the
latest OS.

As part of the upgrade, we pick up a migration to EC2Launch Version 2.
This has a different config mechanism. So we need to port how we manage
the administrator password.

As part of migrating to the new YAML/JSON config file mechanism, we move
the code to the powershell script that is run when the instance first
launches. This ensures that the config is retained during the reboot we
perform as part of building the Windows AMI.

The motivation for this is I'm currently unable to build the Windows
2019 AMI due to an issue installing OpenSSH. This _just works_ on
Windows Server 2022. I have no clue what the root cause is. I think
it might have something to do with Microsoft not publishing the files
in the right location.
