Get rid of most of the guts of the base class and just leave it as a
vtable. We can also drop some of wsi_display_fence. One functional
change here is that we're now using VK_SYSTEM_ALLOCATION_SCOPE_INSTANCE
which is more correct anyway because, thanks to the funky reference
counting we do with destroyed and event_received, its lifetime is tied
to the physical device, at best.

For a long time, our Vulkan WSI code has acted as something of a layer.
The WSI code calls into various Vulkan entrypoints inside the driver to
create images, allocate memory, etc. It then implements the API-facing
interface almost entirely. The only thing the driver has to provide is
little wrappers that wrap around the WSI calls to expose them through
the API.
However, now that we have a common dispatch framework, we can implement
entrypoints directly in the WSI code. As long as the driver uses
vk_instance, vk_physical_device, and vk_device, we can provide common
wrappers for the vast majority of entrypoints. The only exceptions are
vkAcquireNextImage, vkQueuePresent, vkRegisterDeviceEventEXT, and
vkRegisterDisplayEventEXT because those may have to manually poke at
synchronization primitives. We provide wrappers for vkAcquireNextImage
and vkQueuePresent because some drivers can use the default versions.
For now, we're intentionally avoiding any link-time dependencies between
WSI and the common code. We only use VK_FROM_HANDLE and associated
inline helpers and vk_physical_device has a pointer to a wsi_device.
Eventually, we may tie the two together closer, but this lets us get 95%
of the way there without reworking the universe.

The idea behind it is that it's supposed to provide a hint to the
application in a multi-GPU setup to indicate which regions of the screen
are being scanned out by which GPU so a multi-device split-screen
rendering application can render each part of the screen on the GPU that
will be presenting it and avoid extra bus traffic between GPUs. On a
single-GPU setup or one which doesn't support this present mode, we need
to do something. We choose to return the window size (or a max-size
