fix(dimension): set width=0, height=0 in createHiddenSvgNode

[williaster]

🐛 Bug Fix
This fixes an issue in @superset-ui/dimensions where the hidden svg used for text measurement has a non-zero width/height, and can result in the svg affecting layout even though it has position: absolute. In our case this actually causes an infinite measurement loop where

1. the svg is added, resulting in a browser scroll bar
2. the svg is removed, making the scroll bar go away
3. the screen width change in 2) from the scroll bar going away triggers the ResizeObserver of a parent component, updating the chart and goes back to 1)

I updated it to mirror what we have in @vx/text which was fixed here.
