This PR implements EIP 3529

Constant Value
FORK_BLOCK TBD
NEW_MAX_REFUND_QUOTIENT 5

For blocks where block.number >= FORK_BLOCK, the following changes apply.

  1. Remove the SELFDESTRUCT refund.
  2. Replace SSTORE_CLEARS_SCHEDULE with SSTORE_RESET_GAS + ACCESS_LIST_STORAGE_KEY_COST (4,800 gas as of EIP-2929 + EIP-2930)
  3. Reduce the max gas refunded after a transaction to gas_used // NEW_MAX_REFUND_QUOTIENT
