Semantic's Define pin should be true by default and optional

[sebescudie]

Hey there,

If one wants to create a custom semantic, they should the Semantic node and set the Define input to true.

This feels a bit convoluted since if you're using the Semantic node as is, you obviously want to define the semantic.

Could we do the thing the other way around?

• Make Define true by default and hide the pin so that the user does not have to set it
• When using Semantic inside a Variable node (like Color), reveal the pin and set it to false. There we don't care to do it manually because the user does not have to deal with what's inside the node.
