Update clang-tidy to include some more recent rules..

[hzeller]

Also add the run-clang-tidy-cached.cc script (which is in c++ for ease of maintenance) which allows to cache the output, so reprocessing files is much faster.

---

The cache script can be found on https://github.com/hzeller/dev-tools and is essentially just a non-modified drop-in here (except the configuration in line 118 that says to start searching in src/)

I've not removed the old run-clang-tidy.sh script, as it has the functionality to run with a "limited" set of rules.

While at it , update the .clang-tidy rules to include some more wildcards, but also remove an old option that does not work anymore with current clang-tidy.

Due to the caching, only changed files will be re-processed, and if there are no changes, the output is essentially instant. When it processes files, it uses all cores on the machine.

The script is written in C++, but it self-compiles, so with the executable bit flag set, it can be invoked directly like this:

$ .github/bin/run-clang-tidy-cached.cc
Cache dir "~/.cache/clang-tidy/Surelog_v18_ae752712"
