refactor(style): switch-case formatting, "uncrustify:indent-off" #15669

* refactor: disable formatting for attribute in macro
* fixup: disable/enable uncrustify with uncrustify:indent-off/on
* fixup: stop indenting contents inside braces in case
* fixup: remove case brace if no variable declaration
