Fixes: #53654.
Release justification: bug fix.
Release note (bug fix): CockroachDB could previously crash when
evaluating queries with window functions with GROUPS mode of framing
when OFFSET FOLLOWING boundary was used and when the offset was a very
large value such that it could result in an integer overflow. This is
now fixed.
