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
different with this option enabled, but I erred on the side of
caution by keeping the most inclusive wording.
