[Eval] Integrate MLE Bench Into Eval Harness

[xingyaoww]

What problem or use case are you trying to solve?

OpenAI released MLE Bench: https://arxiv.org/pdf/2410.07095, which evaluated an earlier version of OpenHands. We should try to integrate the benchmark to our eval harness: https://github.com/All-Hands-AI/OpenHands/tree/main/evaluation

The code that was used to evaluated OpenHands on MLE Bench is available here: https://github.com/openai/mle-bench/tree/main/agents/opendevin
