KVM: page track: introduce kvm_slot_page_track_{add,remove}_page
These two functions are the user APIs:
- kvm_slot_page_track_add_page(): add the page to the tracking pool
after that later specified access on that page will be tracked
- kvm_slot_page_track_remove_page(): remove the page from the tracking
pool, the specified access on the page is not tracked after the last

Both of these are called under the protection both of mmu-lock and
kvm->srcu or kvm->slots_lock
