Replace Windows Setup with DISM wrapper

[dubyatp]

Here's an interesting idea, so as noted in #226 -- with the latest 24H2 build of Windows 11, the new windows setup will just fail mid-install when trying to install Tiny11 Core. I was able to install Tiny11 Core using the "manual" methods of creating partitions in diskpart and installing them with DISM.

This might be a bit out-of-scope for Tiny11 (and if so, i'll probably create my own project for it), but how about a PowerShell based diskpart and DISM wrapper for installing Tiny11, similar to the simplistic installation screen of Windows 2000 which was also the "classic" installation screen on XP if you chose it in nLite.

Just a simple GUI in WinPE that lets you choose your partition setup, set your product key, perhaps set a local user/password to skip OOBE all together(?), and away you go.
