radv: enable radv_zero_vram for Hammerting

radv: enable radv_zero_vram for Hammerting

This native Vulkan game is broken, it has TON of Vulkan validation
errors and hangs without RADV_DEBUG=zerovram. Also tested with PRO
and AMDVLK.

The application name is also not really descriptive but the executable
name 'boot.exe' is worst.
