Something to keep in mind:

Upstream libplacebo has had native support for OpenGL for quite a while
now, and is currently gaining native D3D11 support. My long-term goal
for this module was to remove the vulkan dependency completely and just
make it ingest a `pl_gpu` and a `pl_swapchain`, with platform-specific
modules providing that capability.

This way, the libplacebo-based renderer can also be used on platforms
without native vulkan drivers. This commit is going a bit in the
opposite direction of that, by making `display.c` even more dependent on
vulkan specifics.
