LibSQL: Separate parsing of common-table-expression list

Browse source 
Statements like SELECT, INSERT, and UPDATE also optionally include this
list, so move its parsing out of parse_delete_statement(). Since it will
appear before the actual statement, parse it first in next_statement();
then only parse for statements that are allowed to include the list.
