I commented on this in the office, but I think this whole thing would be
cleaner if we just clearly documented address ranges in anv_private.h with
a good comment. Something like
#define LOW_HEAP_BASE_ADDRESS 4096
#define LOW_HEAP_SIZE ((3ull << 30) - 4096)
#define DYNAMIC_STATE_POOL_ADDRESS
The state_pools reserve virtual address space of the full
BLOCK_POOL_MEMFD_SIZE, but maintain the current behavior of
growing from the middle.
