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