feat: attester committees data extractor (BFT-434) (matter-labs#2684)

Extraction of the attester committee from consensus registry state. If
consensus registry address is not specified, we fall back to attester
committee from genesis. This pr does NOT enable the dynamic attestation,
as the registry address needs to be added to the main node config first.
