vm_memory: A crate to hold vm-specific memory objects Move GuestAddress and GuestMemory to a new crate for VM memory. This will make separating sys_util and crosvm independent making it easier to use sys_util functions outside of crosvm.

devices: snapshot and restore for guest memory `crosvm snapshot take ...` will write the contents of guest memory to a file and `crosvm restore apply ...` will read that file to overwrite guest memory. To start with, the file is chosen by adding a ".mem" extension to the snapshot file path. We should consider a better approach in the future, maybe put them both in a tar file or have the user supply a directory instead of a file path.

vm_memory: skip holes when snapshotting RAM On linux, we can use `lseek`'s `SEEK_DATA` and `SEEK_HOLE` features to skip hole in files. On a freshly booted VM, it is common that much of the RAM is untouched. For an Ubuntu test VM 8 GiB RAM, this reduced the snapshot size from 8 GiB to 655 MiB and the snapshot time from 12s to 270ms. Restore time is tricky to measure exactly, but it feels much faster.
