[Relax][Transform] Preserve param names in LiftTransformParams (#16594)

* [Relax][Transform] Preserve param names in LiftTransformParams

The `relax.transform.LiftTransformParams` pass splits apart a relax
function, extracting the steps that could be performed at
compile-time.  Prior to this commit, the transformed parameters were
named `param0`, `param1`, and so on.

This commit updates the `LiftTransformParams` pass to preserve any
human-readable parameter names.  The parameter names for the updated
function are taken from the original parameter names, if no
transformation is performed, or from the internal variable binding, if
a transformation is applied.  This implementation uses `LambdaLift`
internally, relying on the changes made in
#16306.

* Update based on review comments
