MDEV-28152 Create sequence truncating out-of-bound max/minvalue

This is item 2 of MDEV-28152. When creating a sequence with a huge
minvalue / maxvalue, truncate it to the nearest valid value for the
type, i.e. LONGLONG_MAX - 1 for values >= LONGLONG_MAX and
LONGLONG_MIN + 1 for values <= LONGLONG_MIN
