Merge bitcoin/bitcoin#25126: test: add BIP157 message parsing support (via MESSAGEMAP)

5dc6d9207778c51c10c16fac4b3663bc7905bafc test: make BIP157 messages default-constructible (MESSAGEMAP compatibility) (Sebastian Falbesoner)
71e4cfefe765c58937b3fd3125782ca8407315d2 test: p2p: add missing BIP157 message types to MESSAGEMAP (Sebastian Falbesoner)

Pull request description:

  The script [message-capture-parser.py](https://github.com/bitcoin/bitcoin/blob/master/contrib/message-capture/message-capture-parser.py) currently doesn't support parsing the BIP157 messages `getcfilters`, `getcfheaders` and `getcfcheckpt`, e.g.
  ```
  $ ./contrib/message-capture/message-capture-parser.py msgs_recv.dat
  ...
      WARNING - Unrecognized message type b'getcfcheckpt' in /home/thestack/bitcoin/msgs_recv.dat
  ...
  ```

  This PR fixes this by adding the missing message type mappings to the [`MESSAGEMAP`](https://github.com/bitcoin/bitcoin/blob/225e5b57b2ee2bc1acd7f09c89ccccc15ef8c85f/test/functional/test_framework/p2p.py#L95-L127) in the test framework and add default-constructors for the corresponding `msg_`... classes.

  Without the second commit, the following error message would occur:
  ```
    File "/home/thestack/bitcoin/./contrib/message-capture/message-capture-parser.py", line 141, in process_file
      msg = MESSAGEMAP[msgtype]()
  TypeError: __init__() missing 2 required positional arguments: 'filter_type' and 'stop_hash'
  ```
