IMPALA-7618: Accept reversed comparators (> / >=) in range partition bounds

The SQL parser only accepted '<' and '<=' operators in range partition
bounds, rejecting logically equivalent forms like 'VALUES >= X' and
'X > VALUES'. This created an inconsistency where SHOW RANGE PARTITIONS
displayed bounds using '>=' notation that couldn't be used in DDL.

Fix the parser grammar to accept '>' and '>=' in both opt_lower_range_val
and opt_upper_range_val, marking them as reversed. A new RangeBound class
carries a 'reversed' flag so that createFromRangeWithNormalization() can
swap bounds into their correct semantic positions before constructing the
RangePartition. Both forms now produce identical internal representations.
