Passing the CPUID leafs with the topology is integrated into the common
mechanism of setting and patching CPUID in Cloud Hypervisor. All the
CPUID values will be passed to the hypervisor through the register
intercept call.

On KVM this is provided by an ioctl, on MSHV this is constant. Although
there is a HV_MAXIMUM_PROCESSORS constant the MSHV ioctl API is limited
to u8.

Recently generated mshv-bindings has most of the registers
renamed. This patch renames some of the MSHV registers.

It seems like these examples were always intended to be doctests,
since there are lines marked with "#" so that they are excluded from
the generated documentation, but they were not recognised as doc tests
because they were not formatted correctly.
The code needed some adjustments so that it would actually compile and
run as doctests.

With this bump there was a change in one of the externally exposed
variable. Thus, the use of that variable in CLH must be adjusted
accordingly.

This requires making get/set_lapic_reg part of the type.
For the moment we cannot provide a default variant for the new type,
because picking one will be wrong for the other hypervisor, so I just
drop the test cases that requires LapicState::default().

CpuId is an alias type for the flexible array structure type over
CpuIdEntry. The type itself and the type of the element in the array
portion are tied to the underlying hypervisor.
Switch to using CpuIdEntry slice or vector directly. The construction of
CpuId type is left to hypervisors.
This allows us to decouple CpuIdEntry from hypervisors more easily.
No functional change intended.

We only need to do this for x86 since MSHV does not have aarch64 support
yet. This reduces unnecessary code churn.

VmState was introduced to hold hypervisor specific VM state. KVM does
not need it and MSHV does not really use it yet.
Just drop the code. It can be easily revived once there is a need.

It is however only used for KVM right now because MSHV does not need it
yet.
Nonetheless a stub MSHV constructor should be there and get/set
functions should be implemented for MSHV.

By default Microsoft Hypervisor send a GP to the guest if it tries
read/write an unimplemented MSR from the hypervisor prospective. Instead
change this behavior to ignore read/write operations for unimplemented
MSRs

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

Move this enum from vm-device to hypervisor crate so that hypervisor
crate does not gain an extra dependency.
