numa: deprecate implict memory distribution between nodes
Implicit RAM distribution between nodes has exactly the same issues as:
"numa: deprecate 'mem' parameter of '-numa node' option"
only with QEMU being the user that's 'adding' 'mem' parameter.
Deprecate it, to get it out of the way so that we could consolidate
guest RAM allocation using memory backends making it consistent and
possibly later on transition to using memory devices instead of
adhoc memory mapping for the initial RAM.
