Add A output boolean on the bake node to check if bake exist

For certain geometry node setups that generate high density meshes or have complex calculations I believe it would be best to add a boolean output onto the bake node. As in the current iteration when there is no current bake file , the node tree is executed as usual on every change to the modifier, this could lead to some unfortunate crashes when initialy applying a modifer to a object.

Adding a boolean output to check if a bake file exist would be a good flexible solution to this as it would allow the creator of the graph to ouput to a switch and have further control of the output (this could be something like making it show a text mesh saying "please bake for result" or showing a simplified version of the mesh )
