Subject: [PATCH] driconfig: add a workaround for Hades (Vulkan backend)

Vulkan backend of Hades can only handle at most 3 swapchain images.

It affects all drivers after below commit:
04d654a5d0b7bb4a072f515f6fbe2a686fc7f7f8

and then only affects specific driver backend which enables
extra_xwayland_image in wsi device options after below commit:
