KVM: VMX: Move vt_apicv_pre_state_restore() to posted_intr.c and tweak name

In preparation for a cleanup of the kvm_x86_ops struct for TDX, all vt_*
functions are expected to act as glue functions that route to either tdx_*
or vmx_* based on the VM type. Specifically, the pattern is:

vt_abc:
    if (is_td())
        return tdx_abc();
    return vmx_abc();

But vt_apicv_pre_state_restore() does not follow this pattern. To
facilitate that cleanup, rename and move vt_apicv_pre_state_restore() into
posted_intr.c.

Opportunistically turn vcpu_to_pi_desc() back into a static function, as
the only reason it was exposed outside of posted_intr.c was for
vt_apicv_pre_state_restore().

No functional change intended.
