clang-format: re-format for clang-19

clang-format-19 isn't compatible with the clang-format-18 output, so we
need to reformat the code with the latest version.  A few parameters
in clang-tidy have been deprecated, so adjust the style file
accordingly.

See Ie2f6eb3b043f2d655c9df806815afd7971fd0947 for updated style.
See I88192b41ab7a95599a90915013579608af7bc56f for clang-19 enablement.
