This commit furthers some of the changes that were started in rBb9febb54a492 and subsequent commits by changing the way surface objects are presented to render engines and other users of evaluated objects in the same way. Instead of presenting evaluated surface objects as an `OB_SURF` object with an evaluated mesh, `OB_SURF` objects can now have an evaluated geometry set, which uses the same system as other object types to deal with multi-type evaluated data. This clarification makes it more obvious that lots of code that dealt with the `DispList` type isn't used. It wasn't before either, now it's just *by design*. Over 1100 lines can be removed. The legacy curve draw cache code is much simpler now too. The idea behind the further removal of `DispList` is that it's better to focus optimization efforts on a single mesh data structure. One expected functional change is that the evaluated mesh from surface objects can now be used in geometry nodes with the object info node. Cycles and the OBJ IO tests had to be tweaked to avoid using evaluated surface objects instead of the newly exposed mesh objects. Differential Revision: https://developer.blender.org/D14550
