fix(verify-bytecode): use local creation code for fork deployment

[yash-atreya]

Motivation

Fixes #8255

Printing wrong verification_type in json result.

Solution

WIP

Print the correct verification_type from the result.

This is only a partial fix though, since the runtime doesn't even match partially with the onchain runtime code. Though it was supposed to in the case of #8255 (comment).

Upon investigating, I observed that; the runtime code that we generate locally by forking has trailing zeros and the onchain runtime code doesn't

Onchain runtime code:

Removing the trailing zeros would match the codes exactly.

@mattsse @klkvr any input here as to why this happens? Need some insight on how to fix this, or maybe it's just an edge case of the compiler?

Removing the trailing zeros would match the codes exactly.

revm adds additional zeroes to the end of bytecode during analysis I believe. you should use Bytecode::original_bytes to get rid of them here:

foundry/crates/verify/src/bytecode.rs

Line 355 in 1e0603f

fork_runtime_code.bytecode(),

Found the bug related to verifying SystemConfig contract #8255 (comment).

We were using the onchain creation code (instead of the locally built creation code) to deploy the contract on the fork and get the runtime code.
