vl: Set machine ram_size, maxram_size and ram_slots earlier

The machine RAM attributes will need to be analyzed during the
configure_accelerator() process. especially kvm_type() arm64
machine callback will use them to know how many IPA/GPA bits are
needed to model the whole RAM range. So let's assign those machine
state fields before calling configure_accelerator.
