The diff between the 22000 and 22621 SDKs is fairly small, but it does include

the latest updates to DirectWrite and DXGI which I make heavy use off.
## Validation Steps Performed
* It builds ✅
Upgrades our SDK from 19041 (Windows 10 20H1) to 22000 (Windows 11 RTM).
The newer SDK is more compatible with /Zc:preprocessor
and will allow us to use newer Windows 11 APIs directly.
