Expose whether can use the regular sort or lexsort for given data type

**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
Yes, I want to use the optimize sort when I can, however there is no way to know if the current sort kernel support the input data type or not

**Describe the solution you'd like**
expose whether I can use the sort or lex sort

**Describe alternatives you've considered**
look at the implementation and duplicate the logic to check, but if there are more types that are supported, I won't know

Start by locating the regular sort and lexsort kernels and the existing checks for supported input data types. Determine how that support information could be exposed and identify the relevant tests; done means callers can reliably choose the supported sort path without duplicating implementation logic.
