[PATCH 3/3] KVM: VMX: Rename posted interrupt prefixes from "vmx" to "vt"

[Sean Christopherson <seanjc@google.com>]

Rename all common posted interrupt APIs that use a "vmx" prefix to instead
use a "vt" prefix to capture that they are used for both VMX and TDX vCPUs.

No functional change intended.
