Support VK_NV_low_latency2

[esullivan-nvidia]

This PR updates the Vulkan xml file to 1.3.267, and adds some additional support for the VK_NV_low_latency2 extension to winevulkan. The only code changes needed are for passing in a valid frame id to fshack's vkQueueSubmit.

What is this for? Are there any consumers of this API out there that will benefit from supporting it?

It would be nice to get the Vulkan version bump upstreamed. Save hassle when rebasing the tree.

Also the custom implementation of vkSetLatencySleepModeNV, it looks like it's there for setting the private low_latency_enabled for fshack. Is there any reason why we don't handle passing .sType and .pNext and set them to hardcoded values?

for the first question, there are PRs on the dxvk and dxvk-nvapi repos to add support for this extension to enable reflex in games, so yes there are consumers

Linking to the related PRs that those are all cross-linked:

https://github.com/doitsujin/dxvk/pull/3690 https://github.com/HansKristian-Work/vkd3d-proton/pull/1739 https://github.com/jp7677/dxvk-nvapi/pull/147

Bump to Vulkan 1.3.267 has been cherry-picked from upstream. This unblocks work on other projects - testing that it works when the supporting driver finally drops. Only the fshack remains but it's not essential and we can iterate on it a bit.

Could you please update this for the experimental 9 or proton 9 branch? Thanks in advance

was able to fix the patch and test against proton 9. Everything is working fine. Here the patch: https://github.com/CachyOS/CachyOS-PKGBUILDS/blob/master/proton-cachyos/proton-cachyos/wine-reflex.patch
