This PR introduces a gasBudget struct to track the available gas for EVM execution. With the upcoming EIP-8037, multi-dimensional gas accounting will be introduced, requiring multiple gas budget counters to be tracked simultaneously. To support this, the counters are grouped into a gasBudget structure. This change is a prerequisite for internal refactoring in preparation for EIP-8037. --------- Co-authored-by: MariusVanDerWijden <m.vanderwijden@live.de>
