core,eth: implement tx-level hooks for tracers (#24510)

Browse Source 
* core,eth: add empty tx logger hooks

* core,eth: add initial and remaining gas to tx hooks

* store tx gasLimit in js tracer

* use gasLimit to compute intrinsic cost for js tracer

* re-use rules in transitiondb

* rm logs

* rm logs

* Mv some fields from Start to TxStart

* simplify sender lookup in prestate tracer

* mv env to TxStart

* Revert "mv env to TxStart"

This reverts commit 656939634b9aff19f55a1cd167345faf8b1ec310.

* Revert "simplify sender lookup in prestate tracer"
