machine: introduce memory-backend property

Property will contain link to memory backend that will be
used for backing initial RAM.
Follow up commit will alias -mem-path and -mem-prealloc
CLI options into memory backend options to make memory
handling consistent (using only hostmem backend family
for guest RAM allocation).
