8914ce9da8 build: Bump mshv-ioctls from 10d0c52 to ef01a5a 
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.

05e5106b9b hypervisor x86: provide a generic LapicState structure 
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().

45fbf840db hypervisor, vmm: move away from CpuId type 
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.

It is however only used for KVM right now because MSHV does not need it

Nonetheless a stub MSHV constructor should be there and get/set

This return type is not a problem since this function is implemented
only for mshv, but we need to remove the type as the same function will
be implemented for KVM in PR #3575. This commit replaces the
mshv-specific type with `u32`.
