qmp: Expose MachineClass::default_ram_id

If a management application (like Libvirt) want's to preserve
migration ability and switch to '-machine memory-backend' it
needs to set exactly the same RAM id as QEMU would. Since the id
is machine type dependant, expose it under 'query-machines'
result. Some machine types don't have the attribute set (riscv
family for example), therefore the QMP attribute must be
optional.
