vulkan: add POLARIS10 KhronosGroup's Vulkan-Tools' vkcube and LunarG's VulkanSamples' Hologram gfxr traces

Vulkan traces are not device independant. Although gfxreconstruct is working in some portability mode, they will still depend on the exposed extensions at the point of capturing.

We now specify that the existing trace was captured with an Intel gen9 device (Kaby Lake) and add an additional trace captured with an AMD POLARIS10 device.
