Rather than defining the callbacks at the provider instantiation time for the entire lifetime of the provider, this allows for a more granular control of injecting the trace event listener (VMTracer), thus simplifying how the information flows. In the test logic, we no longer tightly couple two classes but have to keep them side by side and we can stop observing the EVM if needed, without paying the runtime cost.

While technically it's a standalone improvement, the https://github.com/NomicFoundation/edr/pull/531 can nicely build on top if it as it will also allow us to conveniently observe the trace whenever needed all at once in Rust (with the Rust port of VmTracer in that PR); it also removes some dead code.
