add vulkan-terakan support

cc @crueter @lucasmz1 can you test this?

Device is recognized:

But does work. Init fails

I can't find any logs despite having enabled them...

@Triang3l This may interest you :)

I can't find Dolphin's logs, but I tried on other emulators and they all give VK_ERROR_INITIALIZATION_FAILED without much more information. Both vkcube and vkmark work totally fine as does OpenGL on Dolphin here. You can get vkcube here: https://github.com/pkgforge-dev/Anylinux-AppImages/releases/download/demo/vkcube+glxgears-demo-x86_64.AppImage

I have yet to test Zink. In case it's important, this is an AMD E-350 which has a TeraScale Radeon HD 6310 built in.

The driver is nowhere close to being ready for use at this point and won't be for at least half a year or even much more, it doesn't even support basic 1.0 functionality like compute shaders. Until it at least passes the CTS for 1.0 (and reports the actual Mesa version rather than 0.0.1 as the driver version), there's no point in attempting to support it.

Anything we can do to help you get data/testing on other hardware? Or is it more like Patiently Waiting until your code Works(TM)?

Thanks for responding @Triang3l hopefully this driver will be ready someday.

The development is largely straightforward except for complicated workarounds for issues like unnormalized texture coordinates being toggled per-instruction rather than per-sampler, just needs pretty complex architectural work mostly, especially in pipeline state and shaders.

Don't worry, I finally have a GPU that supports vulkan
