Check endorsement PoS draw in Protocol

[damip]

Perform a PoS draw check for endorsements in Protocol (funcion note_endorsmenets_from_node).

Outcomes:

• if the (slot, index) matches the endorsement producer => OK
• if there is a mismatch => ignore the endorsement and ban the sender
• if the PoS draw is invalid => also drop the endorsement with an error but don't ban the sender

The corresponding in-header check can be removed from Consensus.
