Always assume isFinalCals is truth when applying constructive modifiers on curves
for viewport display.

It saves plenty of memory when using subsurf modifier which result is getting
converted from CCGDM to CDDM without any benefit. It also syncs behavior of
modifiers with mesh.

Need to keep an eye on constructive modifiers when in edit mode.

Discovered this when was looking into #29973.
