Remove Geometry2d.isSnappable (#2768)

`Geometry2d.isSnappable` isn't used. There's some intended behaviour
here around making it so you can't snap handles to text labels, but it's
not actually working.

This is a breaking change, but given this property doesn't do anything I
don't think it's likely to be heavily depended upon
