Uninline and export Hyper-V's hv_track_root_tdp(), which is (somewhat
indirectly) the last remaining reference to kvm_x86_ops from vendor
modules, i.e. will allow unexporting kvm_x86_ops. Reloading the TDP PGD
isn't the fastest of paths, hv_track_root_tdp() isn't exactly tiny, and
disallowing vendor code from accessing kvm_x86_ops provides nice-to-have
encapsulation of common x86 code (and of Hyper-V code for that matter).
No functional change intended.

Everywhere we use kvm_for_each_vpcu(), we use an int as the vcpu
index. Unfortunately, we're about to move rework the iterator,
which requires this to be upgrade to an unsigned long.
Let's bite the bullet and repaint all of it in one go.

Currently the remote TLB flush logic is specific to VMX.
Move it to a common place so that SVM can use it as well.
