Vulkan: Restrict feedback loop detection to AMD RDNA 3 GPUs

This change restricts feedback loop detection to only be utilized by AMD RDNA 3 GPUs. Performance remains unchanged for these cards, but it alleviates performance issues with other GPUs in circumstances where feedback loops are normally detected. Examples include Paper Mario: TTYD and the Xenoblade games.
