lib/os/cbprintf: Picolibc doesn't support several cbprintf options * Picolibc doesn't provide the %a-only mode. * On advice from security experts, who report numerous vulnerabilities caused by %n in printf specifiers, picolibc never supports this feature. * Picolibc doesn't use cbprintf for C-library compatible functions, instead it provides aliases for the *printfcb functions using stdio names.
