eth/catalyst: add initial OpenTelemetry tracing for newPayload (#33521)
This PR adds initial OpenTelemetry tracing to the Engine API, focusing
on engine_newPayload*.

```
jsonrpc.engine/newPayloadV4 
|  |- engine.newPayload  [block.number, block.hash, tx.count]
|     |- core.blockchain.InsertBlockWithoutSetHead
|        |- bc.processor.Process
|        |  |- core.ApplyTransactionWithEVM  [tx.hash, tx.index]
|        |  |- core.ApplyTransactionWithEVM  [tx.hash, tx.index]
|        |  |- ...  (one per transaction)
|        |  |- core.postExecution
|        |- bc.validator.ValidateState
```
