apic-common: make "id" property a uint32
The getter and setter of TYPE_APIC_COMMON property "id" are apic_common_get_id() and apic_common_set_id(). apic_common_get_id() reads either APICCommonState member uint32_t initial_apic_id or uint8_t id into an int64_t local variable. It then passes this variable to visit_type_int(). apic_common_set_id() uses visit_type_int() to read the value into a local variable, which it then assigns both to initial_apic_id and id. While the state backing the property is two unsigned members, 8 and 32 bits wide, the actual visitor is 64 bits signed. Change getter and setter to use visit_type_uint32(). Then everything's uint32_t, except for @id.
