[PATCH v9 0/2] MR4698: Draft: winewayland.drv: Add unaccelerated pointer support

[Grigory Vasilyev (＠h0tc0d3)]

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.

Based on Proton and Wine-Staging patches by @rbernon.
