Tests show that shell windows are per-desktop, not global. Existing tests also show that new desktops from CreateDesktop do not have a shell window set initially. The Default desktop on WinSta0 does, however.
GetShellWindow ought to return an IShellView's window, but we never actually make one of those for the desktop. However, there is a common pattern (used by e.g. GOG Galaxy) of retrieving an unelevated token by duplicating that of the owner of GetShellWindow, so having any window set at all is a step in the right direction.

To start an ARM64X executable in ARM64EC mode the x64 target machine
needs to be explicitly specified. x64 is also not listed in
SupportedProcessorArchitectures on ARM64EC (also the case on Windows) so drop the check that
requires that.

Some tests reuse the same MP4 stream and are currently passing only because we have the generic byte stream handler fallback. They pass on Windows too, so I'm assuming the stream is seeked before looking for the hints. We could also very well remove the position restore because the media sources are rewinding the stream later too, but I've kept it like it was.
