radv: only expose storageInputOutput16 for chips with double rate fp16

This feature allows to use both 16-bit integers and 16-bit floats
as inputs/outputs.

This disables storageInputOutput16 on GFX8 because only GFX9+ supports
double rate packed math.

This improves consistency regarding other AMD Vulkan drivers.
