Adding hypervisor crate to abstract out Kvm implementation 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.

Implements the Hypervisor trait for Kvm. This adds the ability for getting both supported/emulated cpuids from the kvm hypervisor. In addition, checking the available capabilities for kvm is now implemented. BUG=chromium:1077058 TEST=Added unit tests for each implemented function.

hypervisor: add KvmVm new and try_clone Vms and Vcpus will be try_cloneable and Send, so we can configure on vcpu threads and so IrqChips can reference all Vcpus. To support cloning, collection fields in Vm have been moved into arc mutexes, and Vm and Vcpu are now Sized. Because this breaks object safety, all usage of the traits will be via static binding. Add impl AsRawFd for SafeDescriptor, to get the sys_util ioctl functions working with SafeDescriptor; eventually the functions will change to take SafeDescriptors. Copy set_user_memory_region helper from kvm crate.
