Follow-up to paradigmxyz/reth#26705, which had to use
SystemContract::Otherbecause the enum has no dedicated variants for the Amsterdam system contracts.Adds an
eip8282module with the builder deposit and exit contract addresses and predeploy code (EIP-8282 builder execution requests, introduced in Amsterdam), dedicatedSystemContractvariants for both, and aSystemContract::amsterdam()helper analogous to the existingcancun()andprague()helpers. Addresses and code match geth'sparamsvalues.
