Manual update of the code was needed since memory_displacement() was
deprecated and replaced with either memory_displacement32() or
memory_displacement64().

Add API to the hypervisor interface and implement for KVM to allow the
special TDX KVM ioctls on the VM and vCPU FDs.

These need to be updated together as the kvm-ioctls depends upon a
strictly newer version of kvm-bindings which requires a rebase in the CH
fork.

In particular update for the vmm-sys-util upgrade and all the other
dependent packages. This requires an updated forked version of
kvm-bindings (due to updated vfio-ioctls) but allowed the removal of our
forked version of kvm-ioctls.
The changes to the API from kvm-ioctls and vmm-sys-util required some
other minor changes to the code.

We don't have IrqFd and IOEventFd support in the kernel for now.
So an emulation layer is needed. In the future, we will be adding this
support in the kernel.

Unfortunately it seems patch entries are ignored when obtaining
dependencies from another workspace.
Remove the problematic kvm-ioctls and kvm-bindings patch entries and use
the forked repository directly.

For efficiently emulating x86 instructions, we need to build and pass a
CPU state copy/reference to instruction emulation handlers. Those handlers
will typically modify the CPU state and let the caller commit those
changes back through the PlatformEmulator trait set_cpu_state method.
Hypervisors typically have internal CPU state structures, that maps back
to the correspinding kernel APIs. By implementing the CpuState trait,
instruction emulators will be able to directly work on CPU state
instances that are directly consumable by the underlying hypervisor and
its kernel APIs.

Instead of having the hypervisor crate embedding Cloud-Hypervisor forks
from the rust-vmm project, it's more appropriate to leave the rust-vmm
references in the hypervisor crate, and have the root Cargo.toml being
patched.

Run loop in hypervisor needs a callback mechanism to access resources
like guest memory, mmio, pio etc.
VmmOps trait is introduced here, which is implemented by vmm module.
While handling vcpuexits in run loop, this trait allows hypervisor
module access to the above mentioned resources via callbacks.

Based on the way KVM_GET_MSRS and KVM_SET_MSRS work, both function are
very unlikely to fail, as they simply stop looping through the list of
MSRs as soon as getting or setting one fails. This is causing some
issues with the snapshot/restore feature, as on some platforms, we only
save a subset of the list of MSRs, leading to unproper way of saving the
VM.
The way to address this issue is by checking the number of MSRs get/set
matches the expected amount from the list. In case it does not match, we
simply ignore the failing MSR and continue getting/setting the rest of
the list. By doing this by iterations, we end up getting/setting as many
MSRs as the platform can support.

This Vcpu trait should be implemented by each underlying hypervisor.
Previously created hypervisor object should create the VM based on
already selected hypervisor and Vm object should create this vcpu
object based on same hyperviosr. Each of this object should be
referenced by trait object i.e <dyn Vcpu>.

The purpose of this trait is to add support for other hypervisors than
KVM, like e.g. Microsoft Hyper-V.
Further commits will define additional hypervisor related traits like
Vcpu and Vm. Each of the supported hypervisor will need to implement all
traits defined from the hypervisor crate.
