Add vulkan builds for x86_64

[alaviss]

Vulkan images at https://quay.io/repository/ramalama/vulkan?tab=tags are only built for aarch64.

I've confirmed that the associated Containerfile can be built and works flawlessly with ramalama (using --image and --gpu flags) on x86_64 with very good performance (tested with a RX 580, not supported by ROCm).

Actually I didn't know Vulkan can do machine learning stuff, so I decided to benchmark my Vega 56 GPU and compare with ROCm. I've found that Vulkan is faster than ROCm.
