Merge bitcoin/bitcoin#24849: lint: Convert lint-logs.sh to Python

e9d2771 lint: Convert lint-logs.sh to Python (Dimitri)

Pull request description:

  A  port of `/test/lint/lint-logs.sh` to a Python-script as part of the request of #24783 . Checked for output-consistency.

  Removed all non-explicit exceptions (i.e. `...`, `LogPrint()`, and `LogPrintf()`) because they weren't needed anymore, except for one single case in a comment in `/src/random.cpp` which I removed because it was quite useless anyway (the comment, not the file).
