fix(simulation): don't use abi-generated EntryPoint bytecode

[dphilipson]

This reverts commit 275414d.

We need the v0.6 entry point bytecode so we can use it in state overrides during call gas estimation. In a previous commit, we started using bytecode generated by abigen to avoid hardcoding the entry point bytecode or fetching it from on-chain on every run. For unknown reasons, the abigen bytecode is faulty and causes reverts with no data, so switch back to using hardcoded bytecode.
