These are needed by microvm too, so move them outside of PC-specific files.
With this patch, microvm.c need not include pc.h anymore.

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

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
f0bb276bf8d5 ("hw/i386: split PCMachineState deriving X86MachineState from it")
and moving the save_tsc_khz field in PCMachineClass to X86MachineClass.
