C++ ts-mode is missing “alignof” as a builtin keyword like sizeof.

Thanks for reporting this. It seems tree-sitter-c/cpp supports '__alignof__', '__alignof', '_alignof', 'alignof', ‘_Alignof’, I can add all of them as keywords. The feature is added in tree-sitter-c in Aug 9, 2023 [1], and appears in v0.20.5.

Eli, what’s the status of Emacs 30 right now? Can I push to emacs-30 and have this change queued for Emacs 30.2? Or should I wait a bit?

If this just adds a bunch of strings to c-ts-mode--keywords, it's okay
to add them on emacs-30.

Thanks.
