cmd/evm: calc base fee if parent data is present (#26051)
Currently, in order to chain together sequential valid t8n transitions the caller must manually calculate the block base fee. This PR adds support for the necessary parent fee market data to calculate the base fee for the current transition.

Concretely, env is extended to accept the following:

    parentBaseFee
    parentGasUsed
    parentGasLimit

Example usage can be found in ./cmd/evm/testdata/25.

cmd/geth, cmd/evm, params: implement Arrow Glacier (EIP 4345) (#23810)
This PR adds support for ArrowGlacier, as defined by

    https://github.com/ethereum/execution-specs/blob/master/network-upgrades/mainnet-upgrades/arrow-glacier.md
    https://eips.ethereum.org/EIPS/eip-4345

> Starting with FORK_BLOCK_NUMBER the client will calculate the difficulty based on a fake block number suggesting to the client that the difficulty bomb is adjusting 10,700,000 blocks later than the actual block number.

This also adds support for evm t8n to return the calculated difficulty, so it can be used to construct test.

cmd/evm: add difficulty calculation to t8n tool (#23353)
This PR adds functionality to the evm t8n to calculate ethash difficulty. If the caller does not provide a currentDifficulty, but instead provides the parentTimestamp (well, semi-optional, will default to 0 if not given), and parentDifficulty, we can calculate it for him.

The caller can also provide a parentUncleHash. In most, but not all cases, the parent uncle hash also affects the formula. If no such hash is provided (or, if the empty all-zero hash is provided), it's assumed that there were no uncles.
