Using CPU_FOREACH() marco instead of scaning the entire
local_apics array for fast searching apic.

In struct APICCommonState, there is an id field yet, which was set earlier,
qdev_prop_set_uint8(env->apic_state, "id", env->cpuid_apic_id);
so we use the id field instead of the variable 'apic_no' to represent the
unique apic
index.

Implement x86_cpu_unrealizefn() for corresponding x86_cpu_realizefn(),

When OS eject a vcpu (like: echo 1 > /sys/bus/acpi/devices/LNXCPUXX/eject),
it will call acpi EJ0 method, the firmware will write the new cpumap, QEMU

After ACPI get a signal to eject a vCPU, then it will notify
the vCPU thread to exit in KVM, and the vCPU must be removed from CPU list，
before the vCPU really removed, there will release the all related vCPU objects.

In order to implement 'cpu-del' in the furture.
at first, needing to refactor x86 apic codes.
this converts apic/kvm/xen 's init() callbacks to realize()
and dropping local_apics[] from file hw/intc/apic.c.
moving apic_state field from CPUX86State to X86CPU.
