machine: alias -mem-path and -mem-prealloc into memory-foo backend
Allow machine to opt in for hostmem backend based initial RAM
even if user uses old -mem-path/prealloc options by providing
MachineClass::default_ram_id
Follow up patches will incrementally convert machines to new API,
by dropping memory_region_allocate_system_memory() and setting
default_ram_id that board used to use before conversion to keep
migration stream the same.
