Add libp2p label to chronicles log topics

[LNSD]

Added libp2p topic to the chronicles topics list. For consistency and because this is necessary to filter out all the logs with -d:"chronicles_disabled_topics=libp2p".

There is one logScope: topics which is not being applied/respected by chronicles.

https://github.com/status-im/nim-libp2p/blob/a3e9d1ed80c048cd5abc839cbe0863cefcedc702/libp2p/upgrademngrs/muxedupgrade.nim#L23-L24

I am getting logs from that module. Note that the topics label is not present in the following logs.

@Menduist Do you have any idea how this is possible?

It's a chronicles' "problem" with procedure written inside other procedure. The ugly solution is to also write the logScope inside the parent proc. The pretty solution is to fix this inside chronicles.
