Implement to_expression for non terminals that represent a bind marker. For now each bind marker has a shape describing where it is used, but hopefully this can be removed in the future. In order to evaluate a bind_variable we need to know its type. The type is needed to pass to constant and to validate the value. Signed-off-by: Jan Ciolek <jan.ciolek@scylladb.com>
