Is your feature request related to a problem? Please describe.
There are APIs like split and slice where some of the inputs are host-accessible index ranges. In such cases these ranges may represent indices that are out of bounds, and this can be verified without any introspection.

Describe the solution you'd like
Instead of cudf::logic_error, we should throw std::out_of_range exceptions in these cases.

Describe alternatives you've considered
None

Additional context
This proposal does not indicate that we should try to detect out of range indices in APIs like gather or scatter. Those would require introspection of device data, which is out of scope for libcudf, so behavior in those cases remains undefined.
