Harden handling of unviable forks (#3312) * Harden handling of unviable forks In our current handling of unviable forks, we allow peers to send us blocks that come from a different fork - this is not necessarily an error as it can happen naturally, but it does open up the client to a case where the same unviable fork keeps getting requested - rather than allowing this to happen, we'll now give these peers a small negative score - if it keeps happening, we'll disconnect them. * keep track of unviable forks in quarantine, to avoid filling it with known junk * collect peer scores in single module * descore peers when they send unviable blocks during sync * don't give score for duplicate blocks * increase quarantine size to a level that allows finality to happen under optimal conditions - this helps avoid downloading the same blocks over and over in case of an unviable fork * increase initial score for new peers to make room for one more failure before disconnection * log and score invalid/unviable blocks in requestmanager too * avoid ChainDAG dependency in quarantine * reject gossip blocks with unviable parent * continue processing unviable sync blocks in order to build unviable dag * docs * Update beacon_chain/consensus_object_pools/block_pools_types.nim * add unviable queue test

Fetch by-root request directly from quarantine (#5167) When the requestmanager is busy fetching blocks, the queue might get filled with multiple entries of the same root - since there is no deduplication, requests containing the same root multiple times will be sent out.

This PR removes the queue and directly fetches the blocks to download from the quarantine which solves both problems (the quarantine already de-duplicates and is clean of stale information).

when adding duplicates to quarantine, schedule deepest missing parent (#6112) During sync, sometimes the same block gets encountered and added to quarantine multiple times. If its parent is already known, quarantine incorrectly registers it as missing, leading to re-download. This can be fixed by registering the parent's deepest missing parent recursively. Also increase the stickiness of `missing`. We only perform 4 attempts within ~16 seconds before giving up. Very frequently, this is not enough and there is no progress until sync manager kicks in even on holesky.
