 Avoid cloning linear ST_AsRaster inputs

 Guard curve linearization with a cheap type-tree walk before calling
 lwcurve_linearize. The guard uses liblwgeom's lwgeom_type_arc() predicate
 and only recurses through collection wrappers, so already-linear inputs
 avoid an unnecessary deep clone while nested curve containers still get
 linearized before WKB serialization.
