ef242f52137f2a79a739447251d7759bd4705be0 Allow passing "tried" to rpc addpeeraddress to call CAddrMan::Good() (Jon Atack)

Pull request description:

  This pull adds a `tried` argument to RPC addpeeraddress and a regression test for the recent addrman/asmap changes and issue.

  PR #22697 introduced a reproducible bug in commit 181a1207 that fails addrman consistency checks and causes it to significantly lose peer entries when the `-asmap` configuration option is used.

  The issue occurs upon bitcoind restart due to an initialization order change in `src/init.cpp` in that commit, whereby CAddrman asmap is set after deserializing `peers.dat`, rather than before.

  Issue reported on the `#bitcoin-core-dev` IRC channel starting at https://www.erisian.com.au/bitcoin-core-dev/log-2021-08-23.html#l-263.

  ```
  addrman lost 22813 new and 2 tried addresses due to collisions or invalid addresses
  ADDRMAN CONSISTENCY CHECK FAILED!!! err=-17 bitcoind: ./addrman.h:707: void CAddrMan::Check() const: Assertion `false' failed. Aborted
  ```

  How to reproduce:

  - `git checkout 181a1207`, build, and launch bitcoind with the `-asmap` and `-checkaddrman=1` configuration options enabled
  - restart bitcoind
  - bitcoind aborts on the second call to the addrman consistency checks in `CAddrMan::Check()`

  How to test this pull:

  - `git checkout 181a1207`, cherry pick the first commit of this branch, build, git checkout this branch, run `test/functional/rpc_net.py`, which should pass, and then run `test/functional/feature_asmap.py`, which should fail with the following output:

  ```
  AssertionError: Unexpected stderr bitcoind: ./addrman.h:739: void CAddrMan::Check() const: Assertion `false' failed.
  ```
