anv/allocator: Drop the block_size field from block_pool
Since the state_stream is now pulling from a state_pool, the only thing pulling directly off the block pool is the state pool so we can just move the block_size there. The one exception is when we allocate binding tables but we can just reference the state pool there as well. The only functional change here is that we no longer grow the block pool immediately upon creation so no BO gets allocated until our first state allocation. Reviewed-by: Juan A. Suarez Romero <[email protected]>
