drm/amdgpu: add a BO metadata flag to disable write compression for Vulkan

Browse Source 
Vulkan can't support DCC and Z/S compression on GFX12 without
WRITE_COMPRESS_DISABLE in this commit or a completely different DCC
interface.

AMDGPU_TILING_GFX12_SCANOUT is added because it's already used by userspace.
