eth/tracers: refactor traceTx to separate out struct logging (#24326)

Browse Source 
* eth/tracers: refactor traceTx to separate out struct logging

review fix

Update eth/tracers/api.go

Co-authored-by: Martin Holst Swende <martin@swende.se>

Mv ExecutionResult type to logger package

review fix

impl GetResult for StructLogger

make formatLogs private

confused exit and end..

account for intrinsicGas in structlogger, fix TraceCall test

Add Stop method to logger

Simplify traceTx

Fix test

rm logger from blockchain test

account for refund in structLogger

* use tx hooks in struct logger

* minor

* avoid executionResult in struct logger

* revert blockchain test changes
