feat(consume): add consume engine hive simulator

[spencer-tb]

🗒️ Description

Adds the consume engine hive simulator to EEST. This acts as an equivalent test runner to that of the hive pyspec simulator.

Now we can fill tests and instantly run them against clients executing blocks as engine_newPayloadVX's, to verify that the generated test fixture validates the client implementation.

Additionally it refactors the consume suite with the following:

1. Remove tests_consume and move consumer tests: test_via_engine etc within src/pytest_plugins/consume/
2. Hive specific simulators have there own folder: src/pytest_plugins/consume/hive_simulators/
3. Utilize conftest.py within hive simulators to avoid overlap.
4. Only use a single pytest-consume.ini file.
