AK: Use __builtin_memset() and such to reduce header dependencies

Browse source 
We can use __builtin_memset() without including <string.h>.
This is pretty neat, as it will allow us to reduce the header deps
of AK templates a bit, if applied consistently.

Note that this is an enabling change for an upcoming #include removal.
