Subject: stacktrace: Remove obsolete functions

No more users of the struct stack_trace based interfaces. Remove them.

Remove the macro stubs for !CONFIG_STACKTRACE as well as they are pointless
because the storage on the call sites is conditional on CONFIG_STACKTRACE
already. No point to be 'smart'.
