src: add NFTNL_EXPR_DYNSET_EXPRESSIONS

NFTNL_EXPR_DYNSET_EXPR defines the stateful expression type that
an element stores when added from the packet path.

This patch adds support for the set expression list, which generalizes
NFTNL_EXPR_DYNSET_EXPR.

This patch also adds nftnl_expr_add_expr() to add new expressions to
elements and nftnl_set_expr_expr_foreach() to iterate over the list of
expressions.
