There's a platform limitation that causes us to crash when we rearrange tabs. Xaml tries to send a drag visual (to wit: a screenshot) to the drag hosting process, but that process is running at a different IL than us. For now, we're disabling elevated drag. Fixes #3581

When we're elevated, we disable drag/dropping tabs when elevated, because of a platform limitation that causes the app to _crash_ (see #4874). However, if the user has UAC disabled, this actually works alright. So I'm adding it back in that case. I'm not positive if this is the best way to check if UAC is disabled, but normally, you'll get a [`TokenElevationTypeFull`] when elevated, not `TokenElevationTypeDefault`. If the app is elevated, but there's not a split token, that kinda implies there's no user account separation. If I'm wrong, it's just code, let's replace this with something that does work. ## Validation Steps Performed Booted up a Win10 VM, set `enableLUA` to `0`, rebooted, and checked if this exploded. It didn't. References #4874 References #3581 Work done in pursuit of #11096 Closes #7754 [`TokenElevationTypeFull`]: https://docs.microsoft.com/en-us/windows/win32/api/winnt/ne-winnt-token_elevation_type
