Opening same PR as PK910 opened in go-eth2-client
attestantio#280

Add the cached PTC (Payload Timeliness Committee) window field to the
gloas BeaconState, matching consensus-specs v1.7.0-alpha.4 (PR #4979).

The field is a Vector[Vector[ValidatorIndex, PTC_SIZE],
(2+MIN_SEED_LOOKAHEAD)*SLOTS_PER_EPOCH] that caches precomputed PTC
assignments for the previous, current, and lookahead epochs.
