Remove deprecated RangeF rounding APIs

The rounding APIs on a Range are not used anymore.

We fixed the use cases where the call to Round was incorrect.
Typically, the code was looking for an "enclosing-range" or
and "enclosed-range".

It is preferable to remove the API since it's misleading the devs.
