[DMN Designer] Remove Shape BorderSize and Font BorderSize properties

Offical DMNDI (of spec DMNv1.2) has no support for Shape border size, Font border size. I will not persist this information.

> Did you want these properties removed from the Editor?

> I would say given the current deadlines the safest approach is to temporarily hide and disable them

Acceptance test

• No node type has these properties
• Save and reopen
