Run ASAN in 4xlarge in all shards (#93879)
We used to have ASAN shard 4 and 5 running in 4xlarge because they timed out. With the current issue with test time collecting, I guess the shard allocation has been changed, and there are now timeout from shard 1 to 3. It's better to just have all shards using the same runner for consistency
