Win11's tablet mode is different from Win10's tablet mode in ways both subtle and gross. Avoid unifying them implicitly, and make it clear that they should not be unified _explicitly_ without testing. Unfortunately, Windows 11's API for checking whether the device is in tablet mode is broken -- it requires one to know whether the device is a tablet to interpret the return value, but there is no documented API providing that information. We use a heuristic partly borrowed from Chromium and partly based on independent investigation. As all of the code using WindowsUIUtils effectively only checked for Win10's tablet mode, this commit technically has no functional changes.
