[SPARK-11396] [SQL] add native implementation of datetime function to_unix_timestamp
`to_unix_timestamp` is the deterministic version of `unix_timestamp`, as it accepts at least one parameters. Since the behavior here is quite similar to `unix_timestamp`, I think the dataframe API is not necessary here. Author: Daoyuan Wang <daoyuan.wang@intel.com> Closes #9347 from adrian-wang/to_unix_timestamp.
