Subject: [PATCH] zink: only add MESA WSI structs for specific devices

Some drivers will drop warnings about seeing these structs in the
pNext chain and not handling them. This change makes it so we
only include the structs with Vulkan drivers that are known to
require them for proper behavior (v3dv only for now) to avoid the
warnings.

It should be noted that here we are only supressing the messages
from Zink. Since the Mesa Vulkan WSI code will include these structs,
when native Vulkan Mesa drivers are used without Zink they might
still dump these messages.

Requested by Mike Blumenkrantz.
