Subject: [PATCH 0/2] KVM: VMX: Super early file refactor for TDX

Rename vmx/ops.h to vmx/vmx_ops.h, and move VMX's posted interrupt support
to dedicated files in preparation for future Trust Domain Extensions (TDX)
enabling.

These changes are somewhat premature, as full TDX enabling is months away,
but the posted interrupts change is (IMO) valuable irrespective of TDX.

The value of the vmx_ops.h rename without TDX is debatable.  I have no
problem deferring the change to the actual TDX series if there are
objections.  I'm submitting the patch now as getting the rename upstream
will save us minor merge conflict pain if there are changes to vmx/ops.h
between now and whenever the TDX enabling series comes along.
