lib: consolidate DEBUG_STACK_USAGE option
Most arches define CONFIG_DEBUG_STACK_USAGE exactly the same way. Move it
to lib/Kconfig.debug so each arch doesn't have to define it. This
obviously makes the option generic, but that's fine because the config is
already used in generic code.
It's not obvious to me that sysrq-P actually does anything caution by
keeping the most inclusive wording.
