Avoid processing redundant RPC blocks (#4179)

Browse Source 
## Proposed Changes

We already make some attempts to avoid processing RPC blocks when a block from the same proposer is already being processed through gossip. This PR strengthens that guarantee by using the existing cache for `observed_block_producers` to inform whether an RPC block's processing should be delayed.
