Liam Merwick 2f34ebf222 hw/i386: Move save_tsc_khz from PCMachineClass to X86MachineClass 
Attempting to migrate a VM using the microvm machine class results in the source
QEMU aborting with the following message/backtrace:

target/i386/machine.c:955:tsc_khz_needed: Object 0x555556608fa0 is not an
instance of type generic-pc-machine

abort()
object_class_dynamic_cast_assert()
vmstate_save_state_v()
vmstate_save_state()
vmstate_save()
qemu_savevm_state_complete_precopy()
migration_thread()
migration_thread()
migration_thread()
qemu_thread_start()
start_thread()
clone()

The access to the machine class returned by MACHINE_GET_CLASS() in
tsc_khz_needed() is crashing as it is trying to dereference a different
type of machine class object (TYPE_PC_MACHINE) to that of this microVM.

This can be resolved by extending the changes in the following commit
f0bb276bf8 ("hw/i386: split PCMachineState deriving X86MachineState from it")
and moving the save_tsc_khz field in PCMachineClass to X86MachineClass.
