Implement tracer logic

[zsluedem]

The UserOperation simulation needs Geth debug_traceCall js tracer to collect custom evm operations.
And we need to implement this tracer logic for the simulations.

Here are some other implementations for reference:

1. https://github.com/eth-infinitism/bundler/blob/f5af738e7f95f53b8954d98e777b2c76c6ea9b1f/packages/bundler/src/GethTracer.ts#L18-L37
2. https://github.com/stackup-wallet/stackup-bundler/blob/main/pkg/tracer/types.go#L48-L54

Goal

1. implement Rust serde types for custom json output (Done in https://github.com/Vid201/aa-bundler/blob/feat/uopool/src/contracts/tracer.rs)
2. implement TracerTest.js
