radv: advertise VK_KHR_shader_subgroup_extended_types on GFX8-GFX9 

This extension allows to use subgroup operations with 8 and 16-bits

Untested on GFX6-GFX7, and most of subgroup operations are broken
on GFX10, so don't enable it for now. Not enabled on ACO because
it's still doesn't support 8-bits/16-bits.
