x86/apic/x2apic: Implement IPI shorthands support

Browse source

All callers of apic->send_IPI_all() and apic->send_IPI_allbutself() contain
the decision logic for shorthand invocation already and invoke
send_IPI_mask() if the prereqisites are not satisfied.

Implement shorthand support for x2apic.
