To form a LightClientUpdate, the following historical states and blocks are needed:

• state: the post state of any block with a post-Altair parent block
• block: the corresponding block
• attested_state: the post state of attested_block
• attested_block: the block referred to by block.parent_root
• finalized_block: the block referred to by attested_state.finalized_checkpoint.root, if locally available (may be unavailable, e.g., when using checkpoint sync, or if it was pruned locally)
