Previously, the makeCallVariantGasCallEIP2929 charged the cold account access cost directly, leading to an incorrect gas cost passed to the tracer from the main execution loop. This change still temporarily charges the cost (to allow for an accurate calculation of the available gas for the call), but then afterwards refunds it and instead returns the correct total gas cost to be then properly charged in the main loop.

makeCallVariantGasCallEIP2929charged the cold account access cost directly, leading to an incorrect gas cost passed to the tracer from the main execution loop.This change still temporarily charges the cost (to allow for an accurate calculation of the available gas for the call), but then afterwards refunds it and instead returns the correct total gas cost to be then properly charged in the main loop.
This is the best fix I could come up with that keeps the general wrapper structure intact. Alternatives would be deeper changes to the way EIP-2929 gas cost calculation is conducted.
