Long first iteration time for `meta-llama/Llama-4-Maverick-17B-128E`

Nobody has claimed this yet.

## 🐛 Bug

When running `benchmark_inference.py` the following command leads to ~33 minutes for the first iteration:

```
python thunder/benchmarks/benchmark_inference.py --input-length 2048 --output-length 512 --mode thunder --num-iterations 10 --num-layers 2
```

### To Reproduce

1. Get the latest container up an running;
2. remove 13f7171784d6a953fd02879f325a7facfe124d0d commit by checking out earlier or committing inverse (to avoid #2680)
3. Run inference script with the above command

### Note

Unfortunately, the patch listed in #2677 does not help reducing compile time

[UPDATE] - It seems to be related to many recompilations

Start by running thunder/benchmarks/benchmark_inference.py with the command in the report and measure the first iteration and recompilations. Investigate the reported repeated recompilation behavior, using the earlier commit context and issue #2677 as references. Done means the benchmark no longer spends about 33 minutes on its first iteration, with the improvement verified by the same command.
