vmm: Split structs from logic that make up VmConfig
Place the data structures that are required for constructing a VmConfig into it's own module from the logic that exists to suppot them. This is useful as a consumer of the API can now clearly see what data structures make up the API for creating VMs. This has no functional change and I made no attempt to clean up the ordering (it's as in the original file) nor any other clean up.
