`Withdrawal`s are syntactically similar to a user-level transaction but live in a different domain than user-level transactions.

`Withdrawal`s provide key information from the consensus layer:

1. a monotonically increasing `index`, starting from 0, as a `uint64` value that increments by 1 per withdrawal to uniquely identify each withdrawal
2. the `validator_index` of the validator, as a `uint64` value, on the consensus layer the withdrawal corresponds to
3. a recipient for the withdrawn ether `address` as a 20-byte value
4. a nonzero `amount` of ether given in wei as a `uint256` value.
4. a nonzero `amount` of ether given in Gwei (1e9 wei) as a `uint64` value.

*NOTE*: the `index` for each withdrawal is a global counter spanning the entire sequence of withdrawals.

For each `withdrawal` in the list of `execution_payload.withdrawals`, the implementation increases the balance of the `address` specified by the `amount` given.

Recall that the `amount` is given in units of Gwei so a conversion to units of wei must be performed when working with account balances in the execution state.

This balance change is unconditional and **MUST** not fail.

This operation has no associated gas costs.
