Instead of keeping track of a local array of positions in the modifier stack itself, use the existing edit mode SoA "edit cache" which already contains a contiguous array of positions. Combined with positions as a generic attribute, this means the state is contained just in the mesh (and the geometry set) making the code much easier to follow. To do this we make more use of the mesh wrapper system, where we can pass a `Mesh` that's actually stored with a `BMesh` and the extra cached array of positions. This also resolves some confusion-- it was weird to have the mesh wrapper system for this purpose but not use it. Since we always created a wrapped mesh in edit mode, there's no need for `MOD_deform_mesh_eval_get` at all anymore. That function was quite confusing with "eval" in its name when it really retrieved the original mesh. Many deform modifiers had placeholder edit mode evaluation functions. Since these didn't do anything and since the priority is node-based deformation now, I removed these. The case is documented more in the modifier type struct callbacks.
