KVM: x86/mmu: Revert "Revert "KVM: MMU: add tracepoint for kvm_mmu_invalidate_all_pages""

Now that the fast invalidate mechanism has been reintroduced, restore
the tracepoint associated with said mechanism.

Note, the name of the tracepoint deviates from the original tracepoint
so as to match KVM's current nomenclature.

This reverts commit e65fd3ffef7a56dbf732e35b28d8cb689615210b.
