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.
