Implement runners via Dockerfiles

[ziyadedher]

Right now evm-bench just expects an executable that implements the runner interface. So I guess the executable could call docker and do this. But runners typically just go raw.

I imagine an improvement would be to use mandatory Dockerfiles that can be built and run with an entry point that satisfies the runner interface. The metadata file for runners could point to that Dockerfile.

Some benefits:

• More standardized environment. For example, it becomes a lot easier to make sure the same Python version is running benchmarks.
• Less dependency management. No need to have poetry or go or whatever toolchain installed to build runners anymore!

Do we need to care about performance? I don't think this is that big of a deal since things are mostly meant to be taken relatively anyway. So as long as we're consistent, we're good.
