KVM: x86: Add helpers to handle 64-bit APIC MSR read/writes
Add helpers to handle 64-bit APIC read/writes via MSRs to deduplicate the
x2APIC and Hyper-V code needed to service reads/writes to ICR. Future
support for IPI virtualization will add yet another path where KVM must
handle 64-bit APIC MSR reads/write (to ICR).
Opportunistically fix the comment in the write path; ICR2 holds the
destination (if there's no shorthand), not the vector.
No functional change intended.
