target-i386: Replace custom apic-id setter/getter with static property

Browse source 
Custom apic-id setter/getter doesn't do any property specific
checks anymore, so clean it up and use more compact static
property DEFINE_PROP_UINT32 instead.

Backports commit 2da00e3176abac34ca7a6aab1f5bbb94a0d03fc5 from qemu
