This disables shaderFloat16 on GFX8 because only GFX9+ supports double rate packed math. This improves consistency regarding other AMD Vulkan drivers and it makes no sense to enable that feature without packed math. This also reduces performance with Wolfeinstein Youngblood if fp16 is forced enabled on GFX8, while it's similar on GFX9. We might re-introduce that feature in the future with ACO support if it ends up being faster and correct.
