Sean Christopherson c482f2cebe KVM: x86: Move APIC access page helper to common x86 code ...

Move the APIC access page allocation helper function to common x86 code,
the allocation routine is virtually identical between APICv (VMX) and
AVIC (SVM).  Keep APICv's gfn_to_page() + put_page() sequence, which
verifies that a backing page can be allocated, i.e. that the system isn't
under heavy memory pressure.  Forcing the backing page to be populated
isn't strictly necessary, but skipping the effective prefetch only delays
the inevitable.
