target/i386: Fix sanity check on max APIC ID / X2APIC enablement
The check on x86ms->apic_id_limit in pc_machine_done() had two problems.
Firstly, we need KVM to support the X2APIC API in order to allow IRQ
delivery to APICs >= 255. So we need to call/check kvm_enable_x2apic(),
which was done elsewhere in *some* cases but not all.
Secondly, microvm needs the same check. So move it from pc_machine_done()
to x86_cpus_init() where it will work for both.
The check in kvm_cpu_instance_init() is now redundant and can be dropped.
