[IR] Mark IrConstructorCall as AnnotationMarker

IrConstructorCall is already used to represent both regular constructor
call and annotations.
Implementing AnnotationMarker avoids 'casting' it to this type later on
 in IrTypeSystemContext, which was done with
 a new IrElement implementation. We'd like to
 avoid such implementations, e.g. as so to make the IR hierarchy sealed.
