Merge #19473: net: Add -networkactive option

Browse Source 
2aac093a3d test: Add test coverage for -networkactive option (Hennadii Stepanov)
3c58129b12 net: Log network activity status change unconditionally (Hennadii Stepanov)
62fe6aa87e net: Add -networkactive option (Hennadii Stepanov)

Pull request description:

  Some Bitcoin Core activity is completely local (offline), e.g., reindexing.

  The `setnetworkactive` RPC command is already present. This PR adds the corresponding command-line argument / config option, and allows to start the client with disabled p2p network by providing `-networkactive=0` or `-nonetworkactive`.

  This was done while reviewing #16981.
