Add a pipelined writeback unit for increased bandwidth and limit acquires to avoid tilelink deadlock

We should PR this to mainline boom instead to not muddy the water of academic results between what NTNU publishes and what the rest works with. I think this can be useful for everybody else, and since you made configuration switches, the acceptance will be straightforward. |

Release Notes
This PR includes two related additions. One is adding a pipelined writeback unit which improves memory bandwidth for eviction-heavy applications. The second is adding an option for not issuing Tilelink acquires while a Tilelink release is in progress, which avoids a deadlock experienced while devoloping the pipelined writeback unit.
