Fix for [#24374] VSE: Reassign Inputs ignores selection order.

* No way currently to know the order of effect inputs, so I added a swap operator for the inputs.
* Also added the effect inputs to the strip property panel (weren't even in rna before). These are not yet editable, but can be very helpful in determining what the inputs are if the strip is too short to see the name in the timeline.
