core, miner: remove PostChainEvents (#19396)

Browse Source 
This change:

- removes the PostChainEvents method on core.BlockChain.
- sorts 'removed log' events by block number.
- fire the NewChainHead event if we inject a canonical block into the chain
  even if the entire insertion is not successful.
- guarantees correct event ordering in all cases.
