Fall back to other peers after a failed lookup download

Test peer fallback after a failed lookup download

Merge remote-tracking branch 'sigp/unstable' into lookup-ancestor-blocks

Address review: drop peer-fallback, guard future-slot blocks, fold anchor handling into get_parent_import_status

Keep anchor special-case out of consensus get_parent_import_status

Address review: BlocksByHead tuple variant, drop request-count tiebreaker, finality uses Failed, lookup tidy-ups

Use build_chain_and_trigger_last_block helper in by-head count test
