Add arch-agnostic traits Vm and Vcpu. Add arch-specific traits
HypervisorXXX, VmXXX, VcpuXXX, with impls for KVM.

This is a separate hypervisor crate for interacting with Kvm in an
abstract manner. The intention is to not leak the internals of kvm
with its specific calls in various places in the codebase. Currently,
this just creates an initial structure for adding various
implementations over time.
In addition, a SafeDescriptor class is added, that wraps a raw file
descriptor safely, without needing to wrap it in the rust file class.
The intention is to use this for non file raw descriptors.

TEST=added a basic kvm test that creates a Kvm struct
