To obtain an execution payload, a block proposer building a block on top of a `state` must take the following actions:
1. Set `payload_id = prepare_execution_payload(state, pow_chain, finalized_block_hash, suggested_fee_recipient, execution_engine)`, where:
1. Set `payload_id = prepare_execution_payload(state, pow_chain, finalized_block_hash, safe_block_hash, suggested_fee_recipient, execution_engine)`, where:
* `state` is the state object after applying `process_slots(state, slot)` transition to the resulting state of the parent block processing
* `pow_chain` is a `Dict[Hash32, PowBlock]` dictionary that abstractly represents all blocks in the PoW chain with block hash as the dictionary key
* `finalized_block_hash` is the hash of the latest finalized execution payload (`Hash32()` if none yet finalized)
* `safe_block_hash` is the return value of the `get_safe_block_hash(store: Store)` function call
* `suggested_fee_recipient` is the value suggested to be used for the `fee_recipient` field of the execution payload
