refactor[test]: bypass eth-tester and interface with evm backend directly

[DanielSchiavini]

Depends on #3904 paradigmxyz/pyrevm#13 paradigmxyz/pyrevm#16

What I did

Refactor the test suite to use evm backend directly. Got rid of eth-tester and added support for pyrevm.

How I did it

• Copy the new ABI parser from titanoboa
• Install pyrevm and update tests
• Create an env interface that is implemented with both py-evm and py-revm
• Remove eth_tester

How to verify it

Tests should pass

Commit message

Refactor the test suite to use the EVM backend directly. Get rid of
`eth-tester` and `web3`, add support for pyrevm.

How:
- Create a `BaseEnv` abstraction which has both `py-evm` and `pyrevm`
  backends
- Implementing multiple backends gives us flexibility between EVM
  backends (especially if there is feature disparity between backends,
  e.g. regarding EIP implementation), and additionally serves as a form
  of differential testing by using different backend implementations.
- Add `ABIContract` abstraction to interface between EVM and contracts
- `BaseEnv` and `ABIContract` are substantially "inspired by" titanoboa,
  but we did not introduce titanoboa as a dependency because it
  increases the coupling between `vyper` and `titanoboa` repos.
- Install pyrevm and update tests
- Remove `eth-tester` and `web3` dependencies

Misc/refactoring:
- Prune a bunch of unneeded functionality in `tests/conftest.py`
  - `tx_failed()` does not need to snapshot (that is handled by
    reverting)
  - Protect every test with `env.anchor()`
  - Remove unneeded `get_contract*` duplicate implementations

incredible. thank you!!!

note: this brings average test time from ~14mins to 3-7mins. and i think it opens up a lot of low-hanging fruit to improve CI performance too!
