x86/apic: KVM: Move lapic set/clear_vector() helpers to common code
Move apic_clear_vector() and apic_set_vector() helper functions to
apic.h in order to reuse them in the Secure AVIC guest APIC driver
in later patches to atomically set/clear vectors in the APIC backing
page.
No functional change intended.
