Define rpc_vm_size_array_t and rpc_vm_offset_array_t
When generating stubs, Mig will will take the vm_size_array_t and define the
input request struct using rpc_vm_size_t since the size is variable. This will turn cause a mismatch
between types (vm_size_t* vs rpc_vm_size_t*). We could also ask Mig to produce
a prototype by using rpc_vm_size_t*, however we would need to change the implementation
of the RPC to use rpc_* types anyway since we want to avoid another allocation
of the array.
