Merge bitcoin#31859: test: Rename send_message to send_without_ping

fa9cf38 scripted-diff: test: Rename send_message to send_without_ping (MarcoFalke)
fa43567 test: Prefer send_and_ping over send_message+sync_with_ping (MarcoFalke)

Pull request description:

  `send_message` is problematic, because it is easy to forget a `sync_with_ping` (or other `wait_until`), leading to intermittent test failures. (Example: bitcoin#31837 (comment))

  There are more uses of `send_and_ping` in the codebase than `send_message`, so in most cases `send_and_ping` is needed anyway.

  For the remaining cases, clearly document that no sync happens by renaming `send_message` to `send_without_ping`.
