presto-odbc driver should support numeric functions 

-  ```SQLGetInfoW``` is updated 
   -  handle ```SQL_NUMERIC_FUNCTIONS``` properly so that user can access Presto's numeric functions.
   - ```SQL_AF_DISTINCT``` is added to ```SQL_AGGREGATE_FUNCTIONS```, which is already supported by Presto
- Nan is handled in the results


It seems like for the numeric functions, the ```driver::translateQuery``` function is enough to handle odbc escape sequences. Tested with Tableau Desktop v8.2.
