anv: Fix INTEL_DEBUG=bat on XeHP

We no longer emit STATE_BASE_ADDRESS in every batch on XeHP, so the decoder might not know what the various base addresses are if it's only looking at a single batch. Fortunately, they also never change, so we can just emit them once here.

On earlier platforms, initializing them here should be harmless. We'll emit STATE_BASE_ADDRESS if we change them, which will update these.

Thanks to Iván Briano for catching this.
