The main goal here is to rename things in a way that makes sense for
simulation baking, but also for the upcoming bake node.
This also removes some versioning code from 3.6 which initialized the
default bake path. Baked data from back then can't be loaded anymore
anyway, and the way the default path is generated is different now as well.
