radv: force enable VK_AMD_shader_ballot for Wolfenstein Youngblood
This gives a nice boost, +20% at this time on my Vega 56. Shader
ballot should be enabled by default at some point but it reduces
performance a bit (-6%) with Wolfeinstein II. Enable it only for
Youngblood at the moment, like what we did for Talos in the past.
As a bonus point, it gets rid of some minor artifacts that only
happens when ballot is disabled for some reasons.
