kernel: add k_mem_map() and related defines

Browse source 
This will be the interface for mapping memory in the kernel's
part of the address space, which is guaranteed to be persistent
regardless of what thread is scheduled.

Further code for specifically managing virtual memory will end up in
kernel/mmu.c.

Further defintions for memory management in general will end up
in sys/mem_manage.h.
