CMake: Hide KMALLOC_VERIFY_NO_SPINLOCK_HELD so folks don't find it

Browse source 
Since I introduced this functionality there has been a steady stream of
people building with `ALL_THE_DEBUG_MACROS` and trying to boot the
system, and immediately hitting this assert. I have no idea why people
try to build with all the debugging enabled, but I'm tired of seeing the
bug reports about asserts we know are going to happen at this point.

So I'm hiding this value under the new ENABLE_ALL_DEBUG_FACILITIES flag
instead. This is only set by CI, and hopefully no-one will try to build
with this thing (It's documented as not recommended).

Fixes: #7527
