There is no need to include serde_derive separately,
as it can be specified as serde feature instead.

The variable tmp was never initialized. Calling assume_init when the
content is not yet initialized causes immediate undefined behaviour.
We also cannot create any intermediate references because they will be
subject to the same requirements for references -- the referred object
must be valid.

The OneRegister literally means "one (arbitrary) register". Just call it
"Register" instead. There is no need to inherit KVM's naming scheme in
the hypervisor agnostic code.

This commit adds methods to save/restore AArch64 vCPU registers,
including:
1. The AArch64 `VcpuKvmState` structure.
2. Some `Vcpu` trait methods of the `KvmVcpu` structure to
enable the save/restore of the AArch64 vCPU states.

This commit ports code from firecracker and refactors the existing
AArch64 code as the preparation for implementing save/restore
AArch64 vCPU, including:
1. Modification of `arm64_core_reg` macro to retrive the index of
arm64 core register and implemention of a helper to determine if
a register is a system register.
2. Move some macros and helpers in `arch` crate to the `hypervisor`
crate.
3. Added related unit tests for above functions and macros.

Initially the licensing was just Apache-2.0. This patch changes
the licensing to dual license Apache-2.0 OR BSD-3-Clause

Implement the vCPU state getter and setter separately from the initial
KVM Hypervisor trait implementation, mostly for readability purposes.

For each of the traits we are defining kvm related structures
and add the trait implementation to the structs. For more information
please see the kvm-ioctls and kvm-bindings crate.
This is a standalone implementation that does not include the switch of
the Cloud-Hypervisor vmm and arch crates to it.
