 Polish handling of curvilinear geometry types being
 sent to GEOS. GEOS only takes linear types, so all
 curvilinear types need to be (a) stroked and (b)
 re-typed to a linear type. The lwgeom_has_arc() function
 is to exact for that work: it will correctly note
 that curve types with no curve components have no arc.
 So a new broader test for any type that *might* have
 an arc is added, to handle the GEOS transformation
 situation.
 Closes #4796
