MDEV-9979 Keywords UNBOUNDED, PRECEDING, FOLLOWING, TIES, OTHERS should be non-reserved

Adding keywords the following keywords into the "keyword" rules:
- EXCLUDE
- UNBOUNDED
- PRECEDING
- FOLLOWING
- TIES
- OTHERS

They are non-reserved words in the SQL standard (checked in a SQL-2011 draft),
and they don't cause any conflicts in sql_yacc.yy.
