Merge bitcoin/bitcoin#26296: ci: Integrate `bitcoin-tidy` clang-tidy plugin

1c976c691cc4b20f43071aabf36c7afed1571057 tidy: Integrate bicoin-tidy clang-tidy plugin (fanquake)
7de23cceb8ac13fcc709453ef0fa14fb93c460b0 refactor: fix unterminated LogPrintf()s (fanquake)
0a1029aa2946787bfe91a84de882c2dd0de076e9 lint: remove  /* Continued */ markers from codebase (fanquake)
910007995d8603ffc466878856227153a638caff lint: remove lint-logs.py (fanquake)
d86a83d6b8587b0971e66c6910af23dd8c042969 lint: drop DIR_IWYU global (fanquake)

Pull request description:

  Demo of integrating the [bitcoin-tidy](https://github.com/theuni/bitcoin-tidy-plugin), [clang-tidy plugin](https://clang.llvm.org/extra/clang-tidy/) written by theuni into our tidy CI job.

  The plugin currently has a single check, `bitcoin-unterminated-logprintf`. This would replace our current Python driven, `git-grep`-based, `.cpp` file only, lint-logs linter.
