Reformat code according to clang-format-15

[thejohnfreeman]

clang-format-10 is no longer available on the latest version of Ubuntu (23.10). clang-format-15 is the latest version available on the latest Ubuntu GitHub runner image (22.04). It does a much better job formatting requires clauses, for one.

We weren't formatting the few headers ending in .hpp either, which this PR corrects.
