*Note*: The function `initialize_beacon_state_from_eth1` is modified for pure EIP-6110 testing only.
Modifications include:
1. Use `DEPOSITS_EIP_FORK_VERSION` as the previous and current fork version.
1. Use `EIP6110_FORK_VERSION` as the previous and current fork version.
2. Utilize the EIP-6110 `BeaconBlockBody` when constructing the initial `latest_block_header`.
3. Add `deposit_receipts_start_index` variable to the genesis state initialization.
