Add "On resize" interaction

In order to take responsiveness to the next level it would be great if an “On resize” interaction could be added.

This interaction could “conditionally” set the “Variable mode” in order to change font size and weight when resizing a frame. Therefore it would be great to have a “system variable” available that can be used in expressions, which represents the “width” and “height” of the frame that is being resized.

This way we can use the new typographic variables much more and we don’t need any additional plugins of complex setup to achieve the same level of responsiveness.

Hey @Rob56, thanks for the feedback!

We’ll pass this onto our prototyping team for future consideration.
