P2P sync: clean up logging

[CHr15F0x]

Add meaningful spans. This should shorten, unify and improve the value of sync logs be it on p2p client level or at the sync logic level.

[CHr15F0x]

Some sync stages do not communicate important info like: current block number.

Example (thought this should not be a fatal error too):

We do know which peer failed to provide the data although we don't know at which height.
