anv: look into batch bo reloc list looking for BOs to decode

Browse Source 
On DG2 I ran into a case where the surface state was not being decoded
with INTEL_DEBUG=bat. This is because the surface states are not part
of a state pool there anymore. Instead BO are allocate manually and
placed in vma heap.
