Function insert_genesis_history 

pub fn insert_genesis_history<'a, 'b, Provider>(
    provider: &Provider,
    alloc: impl Iterator<Item = (&'a Address, &'b GenesisAccount)> + Clone,
) -> Result<(), ProviderError>
where
    Provider: DBProvider + HistoryWriter + ChainSpecProvider + StorageSettingsCache + RocksDBProviderFactory + NodePrimitivesProvider,
    <Provider as DBProvider>::Tx: DbTxMut,

Inserts history indices for genesis accounts and storage.

Writes to either MDBX or RocksDB based on storage settings configuration, using EitherWriter to abstract over the storage backend.
