core: rename MemoryLimitByPhysicalMemory transient property to MemoryLimitScale

That way, we can neatly keep this in line with the new TasksMaxScale= option.

Note that we didn't release a version with MemoryLimitByPhysicalMemory= yet,
hence this change should be unproblematic without breaking API.
