[Bug 51420] Running any program in Wine causes 100% cpu usage in Xorg

I can confirm matt's patch still work in Wine 7.7.

Commit d171d1116764260f4ae272c69b54e5dfd13c6835 makes GetDeviceCaps reprobe
devices/xrandr and for some reason GetDeviceCaps is called repeatedly in many
cases I've tested (eg. every mouse move in a menu bar triggers it).

It seems making such a reprobe frequently is not good in general since it might
cause drivers to disconnect/reconnect devices (cf.
https://forums.developer.nvidia.com/t/x-server-with-loaded-nvidia-driver-spams-log-files/147203/2),
so it should be done sparingly, perhaps during Wine boot, or perhaps with a
configurable behavior through a reg key.

In this case the external HDMI/DVI connect/disconnect event also introduces a
major performance hit. Even without a secondary monitor, my Xorg.0.log grows a
couple GBs long due to endless "connected / disconnected" messages from the
Nvidia driver.

The real bug (if not a straight Nvidia driver's one) seems to be why
GetDeviceCaps is being called so much repeatedly.
