[Request]: Add D8VK support

[TheEvilSkeleton]

Tell us the problem or your need

Currently, there is no way to run Direct3D 8 titles on Vulkan on Bottles.

Describe the solution you'd like

I'd like to propose integrating D8VK. I don't really know much about it, but we could use it and make it available for those who want to play Direct3D 8 on Vulkan.

Other solutions?

It might be a good idea to wait until AlpyneDreams/d8vk#19 have been solved.

Like with d3d10 "going through" d3d11 in dxvk, d3d8 goes through d3d9 and currently a modified version of that is shipped with each build and it doesn't work with the upstream dxvk dll.
So before the issue above have been solved and d8vk doesn't need to ship it's own version you'd have to juggle both the d8vk d3d9.dll (which might not always be up to date) and the dxvk d3d9.dll

This has been solved now and the next release will only require one DLL. I'll reply to this thread when it's released.

See AlpyneDreams/d8vk#114 for discussion about the differences between the two projects. d8vk is more Linux and Wine oriented. There are still some games where d8vk has issues and d3d8to9 might be good to provide as a backup option.

The next release, version 1.0 is out! You only need one d3d8.dll now, so now would probably be a good time to add it to Bottles.

Bottles devs: I am at your service. Let me know if you need anything to get that done.

Well done on this release! I agree it would be great to have. It does require a bit of work to make it available to Bottles users on our side, and I may be able to do that in the next few days :)

I am pleased to report that d8vk has been upstreamed to dxvk. (doitsujin/dxvk#3411). This means that the next release of DXVK will support D3D8, because d8vk has been merged into dxvk. So for the next dxvk release, Bottles can probably just update dxvk.py to also copy d3d8.dll and update the description of dxvk in the UI to include Direct3D 8.
