Add CMake presets

Nobody has claimed this yet.

We have a collection of sensible build targets, represented by the different jobs in the CI (eg: normal, debug, clang-tidy, ASAN, TSAN). Each includes some common args (`-GNinja`), some explicit args for the target build type (`-DTSAN=ON`), and some further flags to support this (eg excluding other features `-DUSE_SNMALLOC=OFF`, enabling other features `-DWORKER_THREADS=2`, disabling slow tests `-DLONG_TESTS=OFF`).

If one of these fails in CI, and you want to repro locally, you _might_ need _exactly the same arguments_. Currently that's done by finding the correct bit of YAML and copy-pasting.

I think [CMake Presets](https://cmake.org/cmake/help/latest/manual/cmake-presets.7.html) solve this in a cleaner way. So we'd create a `CMakePreset.json` specifying these arguments, and then can simply call `cmake --preset TSAN` either locally or in the CI, to get a consistent collection of args (and metadata and flags and who knows what else might be useful).

Start by comparing the existing CI job YAML for normal, debug, clang-tidy, ASAN, and TSAN builds, including their CMake arguments and flags. Define the corresponding presets in CMakePreset.json so local and CI runs can use commands such as cmake --preset TSAN, and verify that each preset reproduces its existing job configuration.
