Subject: [PATCH] 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.
