Also makes the style guide explicitly comment on void, but this was the intent IIRC because it matches Carbon's `-> ()` (and "always" versus "except for void", which we definitely went back and forth on). Includes adjusting function pointers, which I definitely forget this syntax works sometimes. Excludes utils/tree_sitter/src/scanner.c because it claims to be C, but really we should probably fix that to be cpp.
