Add missing event in PendingComponent span and clean up sync logs (#8033)

I was looking into some long `PendingComponents` span and noticed the block event wasn't added to the span, so it wasn't possible to see when the block was added from the trace view, this PR fixes this.

Additionally I've noticed a lot of noises and confusion in sync logs due to the initial`peer_id` being included as part of the syncing chain span, causing all logs under the span to have that `peer_id`, which may not be accurate for some sync logs, I've removed `peer_id` from the `SyncingChain` span, and also cleaned up a bunch of spans to use `%` (display) for slots and epochs to make logs easier to read.
