feat: use docker image to load solvers and setup the testing environment

[EmperorOrokuSaki]

This pull request uses the solvers package to load a docker container that has various solvers and dependencies of Halmos setup.

thanks @EmperorOrokuSaki, the functionality looks good and I can confirm it works in our CI here:
https://github.com/a16z/halmos/actions/runs/9198938639

since it works, I believe we can merge it as-is but if you're up for it it would be awesome to have a follow-up PR with:

• if possible, two split images:

  • a solvers image that is just ubuntu + yices, z3, bitwuzla, cvc5, etc. (as many solvers as feasible). No python, foundry or halmos, just the smallest image that contains solvers.
  • a halmos image that uses solvers as a base image and has Python, foundry and the latest halmos

• the Dockerfiles in-tree. Since we're going to rely on this in CI, we need to be able to easily update the image with updated dependencies
