Fix T67888: Incorrect Wireframe After Applying SubSurf/MultiRes

Show control edges stores the control edges in the mesh which is
picked up by the draw manager. When applyng a subsurf (or multires) we
don't want that data present in the base mesh. Any rebuilding of the mesh
would overwrite the data anyway.

This patch introduces a new flag for applying modifiers
that can be checked to ignore storing display specific data in
the base mesh.
