* `container: silkeh/clang:18-bookworm` in .github/workflows/format.yml
* clang-tidy auto-fix (trivial, in test only)
* Disable `performance-enum-size` (noisy, low value)
* Temporarily turn off 3 diagnostics (to be tackled one-by-one).
* Add explicit `switch` `default` to resolve clang-tidy `bugprone-switch-missing-default-case`

tests/test_numpy_dtypes.cpp:212:5: warning: switching on non-enum value without default case may not cover all cases [bugprone-switch-missing-default-case]
* Add clang-17 and clang-18 testing.

This existing comment in pybind11/eigen/tensor.h
```
// move, take_ownership don't make any sense for a ref/map:
```
is at odds with the `delete src;` three lines up.
In real-world client code `take_ownership` will not exist (unless the client code is untested and unused). I.e. the `delete` is essentially only useful to avoid leaks in the pybind11 unit tests.
While upgrading to clang-tidy 18, the warning below appeared. Apparently it is produced during LTO, and it appears difficult to suppress. Regardless, the best way to resolve this is to remove the `delete` and to simply make the test objects `static` in the unit test code.
