Subject: lib/: make "Memory Debugging" a menuconfig to ease disabling it all
No need to get into the submenu to disable all "Memory Debugging"-related
config entries.
This makes it easier to disable all "Memory Debugging" config options
without entering the submenu. It will also enable one to see that
en/dis-abled state from the outside menu.
This is only intended to change menuconfig UI, not change the config
dependencies.
