Merge #13417: [net] Tighten scope in net_processing

3339ba28e9 Make g_enable_bip61 a member variable of PeerLogicValidation (Jesse Cohen)
6690a28606 Restrict as much as possible in net_processing to translation unit (Jesse Cohen)
1d4df02b7e [move-only] Move things only referenced in net_processing out of header file (Jesse Cohen)
02bbc05310 Rescope g_enable_bip61 to net_processing (Jesse Cohen)

Pull request description:

  As part of a larger effort to decouple net_processing and validation a bit, these are a bunch of simple scope cleanups. I've moved things out of the header file that are only referenced in net_processing and added static (or anonymous namespace) modifiers to everything possible in net_processing.

  There are a handful of functions which could be static except that they are exposed for the sake of unit testing - these are explicitly commented. There has been some discussion of a compile time annotation, but no conclusion has been reached on that yet.

  This is somewhat related to other prs #12934 #13413 #13407 and will be followed by prs that reduce reliance on cs_main to synchronize data structures which are translation unit local to net_processing
