x86/apic: Prepare x2APIC for using apic::max_apic_id
In order to remove the apic::apic_id_valid() callback and switch to
checking apic::max_apic_id, it is required to update apic::max_apic_id when
the APIC initialization code overrides it via x2apic_set_max_apicid().
Make the existing booleans a bitfield and add a flag which lets the update
function and the core code which switches the driver detect whether the
apic instance wants to have that update or not and apply it if required.
