Continuing the refactors described in T93602, this commit moves the face dot tag set by the subdivision surface modifier out of `MVert` to `MeshRuntime`. This clarifies its status as runtime data and allows further refactoring of mesh positions in the future. Before, `BKE_modifiers_uses_subsurf_facedots` was used to check whether subsurf face dots should be drawn, but now we can just check if the tags exist on the mesh. Modifiers that create new new geometry or modify topology will already remove the array by clearing mesh runtime data. Differential Revision: https://developer.blender.org/D14680
