clang-format `AlignConsecutiveDeclarations: AcrossEmptyLinesAndComments` does NOT work on functions

clang-format 22 (from llvm repo for Debian) is suggesting to break the alignment of `gimp_scroll_get_adjustment_value`. But it should still remain aligned with `gimp_scrolled_preview_thaw` and `gimp_scroll_adjustment_values` since I am using `AlignConsecutiveDeclarations: AcrossEmptyLinesAndComments`

Start with the formatting example in libgimpwidgets/gimpscrolledpreview.h and the attached .clang-format configuration; reproduce the result with clang-format 22. Trace how AlignConsecutiveDeclarations handles function declarations across empty lines and comments. Done means the three gimp_* declarations remain aligned under this option, with regression coverage for the reported case.
