chore(packaging): improve naming of eest modules in `ethereum-execution`

[danceratopz]

As it stands in ethereum-execution@2.18.0rc5.dev1, EEST's packages are exposed at the top-level as our source directories are organized underneath ./src/ethereum_spec_tests:
https://github.com/ethereum/execution-specs/tree/69bfc231862811d5010c884c9a893828dee425de/src/ethereum_spec_tests

I.e., you can do:

uvx --with ethereum_execution==2.18.0rc5.dev1 ipython

then interactively import them as

import cli

for all off:

cli
config
ethereum_clis
ethereum_test_base_types
ethereum_test_checklists
ethereum_test_exceptions
ethereum_test_execution
ethereum_test_fixtures
ethereum_test_forks
ethereum_test_rpc
ethereum_test_specs
ethereum_test_tools
ethereum_test_types
ethereum_test_vm
pytest_plugins

Imo, cli, config and pytest_plugins are too generic and should be changed in some way, shape or form.

But should we prefix everything with ethereum_test?

• Then we have ethereum_clis (which is a good name imo) and ethereum_test_cli (which is very close to ethereum_clis), see also chore(weld): Move src/cli -> src/ethereum_test_cli #2154.

Instead should we namespace everything as ethereum_test.execptions?

First step is have a concept we agree on and then to PR it.

I made a doc of the whole eest dir structure here so we can look at the whole thing all laid out. Feel free to comment there.

My favorite option is to add the prefix to cli, so:

• cli -> ethereum_test_cli
• ethereum_clis -> client_clis

Then we remove the prefix elsewhere. I think pytest_plugins is generic but because we're already in src/ethereum_spec_tests, it seems okay to me. We also run into some weirdness with base_types/base_types.py, which isn't ideal but I think it's managable.

All that said, no strong opinion really :)

tldr - I propose:

      ├── base_types/          # from ethereum_test_base_types
