Adds the registry key `HKEY_CURRENT_USER\Software\Wine\Wayland Driver\unaccelerated_pointer` witch allows raw input. This makes it easier to calculate the same sensitivity in different games, use sensitivity calculators, and easily change values when changing DPI and do not depend on the compositor or OS.
For example, you want to set the sensitivity to half as much, and sensitivity curves in libinput are more difficult to calculate than in the games themselves.
