x86/apic: Get rid of apic->target_cpus
The target_cpus() callback of the apic struct is not really useful. Some
APICs return cpu_online_mask and others cpus_all_mask. The latter is bogus
as it does not take holes in the cpus_possible_mask into account.
Replace it with cpus_online_mask which makes the most sense and remove the
callback.
The usage sites will be removed in a later step anyway, so get rid of it
now to have incremental changes.
