Hypervisor-agnostic structures for the pic, ioapic, lapic, and pit.
These are derived from existing structures in the pic, ioapic, and pit
implementations, as well as from the kvm_sys bindings.
Includes From implementations converting these structures to their
associated KVM structures. Also includes tests for these conversion
implementations.
BUG=chromium:1077058
TEST=added tests to convert kvm structures to hypervisor-agnostic
structures

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.

This new module contains the irqchip trait and it's implementations. The
irqchips will work with the new hypervisor crate to abstract the
interaction between crosvm and kvm.
This just defines the irqchip trait and an empty implementation of the
KvmKernelIrqChip.

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.

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
