perf: `anvil_mine` is much slower than `hardhat_mine`

I attempted to move my testing from `hardhat node` to `anvil`. Some of my testing requires mining a large number of blocks. `anvil_mine` execution time seems to scale linearly relative to block count, whereas `hardhat_mine` with `hardhat node` is nearly constant. See the following benchmarks:

#### Anvil
```Python
In [1]: import timeit

In [2]: [timeit.timeit(stmt=(f'chain.mine({i})'), globals=globals(), number=50) for i in [1, 1
...: 0, 100, 1000]]
Out[2]:
[0.07101033299113624,
0.39050891700026114,
6.034164124997915,
276.3122650830046]
```

#### Hardhat
```Python
In [1]: import timeit

In [2]: [timeit.timeit(stmt=(f'chain.mine({i})'), globals=globals(), number=50) for i in [1, 1
...: 0, 100, 1000]]
Out[2]:
[0.10906625000643544,
0.09370395800215192,
0.0902477499912493,
0.08129970800655428]
```

I'm using:
* `anvil 0.1.0 (0e33b3e 2023-07-26T00:26:08.161934000Z)`
* `hardhat 9.6.7`
* `ape 0.6.14` (for testing)

Start with anvil/src/eth/api.rs at lines 1421-1440 and reproduce the reported anvil_mine benchmarks using the issue's block counts. Compare execution time across those cases and consider the work complete when mining large batches no longer shows the reported linear slowdown relative to the benchmark behavior.
