Mask Off Haswell Devices on Vulkan

[cwfitzgerald]

Similarly to #4709, we should remove all vulkan instances of haswell gpus. These only show up on mesa https://gitlab.freedesktop.org/mesa/mesa/-/blob/242c7a651308f43d5f6f2590717fd72f44eba3ca/src/intel/vulkan/anv_device.c#L769-775. They aren't compliant and will never be compliant. I can't find the post now, but jekstrand said that trying to support vulkan on haswell was a mistake as it gave people the impression it was possible.

Maybe we have an instance flag that disables masking if people really care.

I have a broader patch that should take care of this, I was looking through our issues to see which ones the PR would take care of.

Will put it up soon.

I'm curious why Haswell isn't compliant?

Basically the gen7 hardware doesn't have the features needed to meet vulkan 1.0. On the proprietary drivers, vulkan support only shows up in skylake (gen8)

Oh, that's annoying. I've been doing most of my development on a haswell laptop :(

Wgpu will still work for you, it will just be via GLES 3.2 instead of Vulkan.
