GPU-assisted validation fails due to "uniformAndStorageBuffer8BitAccess" feature

[kvark]

Environment:

• OS: NixOS (Linux 6.6.45)
• GPU and driver version: AMD RADV 24.1.5
• SDK or header version if building from repo:
• Options enabled (synchronization, best practices, etc.): 1.3.283.0

Describe the Issue

When enabling GPU-assisted validation, it fails to activate:

WARNING-GPU-Assisted-Validation(WARN / SPEC): msgNum: 615892639 - Validation Warning: [ WARNING-GPU-Assisted-Validation ] | MessageID = 0x24b5c69f | vkCreateDevice(): gpuav_validate_copies option was enabled, but uniformAndStorageBuffer8BitAccess feature is not available. Disabling option.

Expected behavior

The feature is supported on this platform. If VVL needs it, I'd expect it to silently enable/request it when I'm creating VkDevice instead of expecting me to request some features.

We currently do this for some features, but thanks for pointing this out, I realize some of the newer options (ex gpuav_validate_copies) didn't attempt to just enable it for you
