x86/apic: Provide common init infrastructure
In preparation for converting the hotpath APIC callbacks to static keys,
provide common initialization infrastructure.
Lift apic_install_drivers() from probe_64.c and convert all places which
switch the apic instance by storing the pointer to use apic_install_driver()
as a first step.
