This removes the need to install any specific version of Python or figure out how to configure it by instead asking users to install `uv` and letting it manage Python. Among other advantages, `uv` is designed to be fast enough to embed directly into our scripts. We were already using this in `bench_runner.py` so that the script could import non standard library dependencies. Moving to it for the rest of our Python unifies the approach and will also enable dependencies whenever needed. I've left `github_tools` alone as it has special handling with its own Bazel setup. I've updated the contributing tools to explain the approach here.
