pgsql: Rename grammar nonterminal to simplify reuse

Rename grammar nonterminal to simplify reuse

A list of expressions with optional AS-labels is useful in a few
different places.  Right now, this is available as xml_attribute_list
because it was first used in the XMLATTRIBUTES construct, but it is
already used elsewhere, and there are other possible future uses.  To
reduce possible confusion going forward, rename it to
labeled_expr_list (like existing expr_list plus ColLabel).
