KUDU-379: fix LESS_EQUAL predicates on float and double columns

This commit adds missing implementation of IncrementCell for float and double
columns, which fixes a TS crash when scanning with an inclusive upper-bound
predicate on float or double columns. This commit does not implement
IncrementCell for bool columns, since bool is not incrementable, and range
predicates on bool columns should be dissallowed. A follow up commit will add
the bool fix and extensive tests for predicates on all column types.
