x86: make 64bit have get_apic_id
generalize the x2apic code some more.
let read_apic_id become a macro (later on a function/inline)
GET_APIC_ID(apic_read(APIC_ID))
+#define read_apic_id() (GET_APIC_ID(apic_read(APIC_ID)))
instead of this weird construct:
-#define read_apic_id (genapic->read_apic_id)
