Call lift fresh in valueToTensor (#81927)
`valueToTensor` is invoked in many python apis such as `x[0] = 0.5`, which lifts the 0.5 to a tensor. the problem is described similarly in https://github.com/pytorch/pytorch/pull/81609 (/s/scalar_to_tensor/valueToTensor)
> scalar_to_tensor is not dispatched and thus there is no interposition point for modes to ensure that the resulting tensor is appropriately wrapped. lift_fresh introduces this interposition point. This prevents FakeTensorMode from erroring
