radv: add a no-op version of vkGetPhysicalDeviceToolPropertiesEXT()

It seems the vulkan common runtime code exposes VK_EXT_tooling but
doesn't (yet) have a fallback if the backend doesn't enable this
extension. Implement it as a no-op for a temporary workaround.

This fixes crashes with dEQP-VK.api.tooling_info.*.
