kernel/svc: Implement TotalMemoryUsedWithoutMmHeap/TotalMemoryAvailableWithoutMmHeap

Given we don't currently implement the personal heap yet, the existing
memory querying functions are essentially doing what the memory querying
types introduced in 6.0.0 do.

So, we can build the necessary machinery over the top of those and just
use them as part of info types.
