This will detect the log prints missing a newline, avoiding the logs to
become unreadable.
Under some circumstances there is a need for a non newline terminated
log. In this case the aliases macros `LogPrintToBeContinued()` and
`LogPrintfToBeContinued()` can be used instead to make the intent
explicit. Core uses an inline comment (`/* Continuated */`) for the same
purpose which would cause issues with `clang-format` if the line ends up
being too long.
Backport of core PR12891 and 13153

Note that one of the fix in `net_processing.cpp` doesn't exist in Core
due to PR12218. However this PR is not appropriated for our codebase.
