Merge bitcoin/bitcoin#27581: net: Continuous ASMap health check

Browse Source 
3ea54e5db7 net: Add continuous ASMap health check logging (Fabian Jahr)
28d7e55dff test: Add tests for unfiltered GetAddr usage (Fabian Jahr)
b8843d37ae fuzz: Let fuzzers use filter options in GetAddr/GetAddresses (Fabian Jahr)
e16f420547 net: Optionally include terrible addresses in GetAddr results (Fabian Jahr)

Pull request description:

  There are certain statistics we can collect by running all our known clearnet addresses against the ASMap file. This could show issues with a maliciously manipulated file or with an old file that has decayed with time.

  This is just a proof of concept for now. My idea currently is to run the analysis once per day and print the results to logs if an ASMap file is used.
