Bake Node Accessible in Node Group/Modifier

Make it possible to implement the bake node into a input socket for a node group. This would increase accessibility for quick actions such as baking different sections/multiple node groups easier instead of going into each group, finding the node, baking, going back out and repeating through many node groups. Adding this functionality would also much improve node group asset creation as well, making it easy to bake sections through the modifier stack.
