Is your feature request related to a problem? Please describe.

The changes to the spec in ethereum/consensus-specs#2805 takes care of scenarios at epoch boundary where it was not clear if an attested_header was signed by the current or next sync committee. The update to the spec introduced signatureSlot and updated the light client validator logic.

Signature Slot is being added here #4365

This issue is for updating the light clients verification logic to take care of the epoch boundary situation.
