[SPARK-18892][SQL] Alias percentile_approx approx_percentile ## What changes were proposed in this pull request? percentile_approx is the name used in Hive, and approx_percentile is the name used in Presto. approx_percentile is actually more consistent with our approx_count_distinct. Given the cost to alias SQL functions is low (one-liner), it'd be better to just alias them so it is easier to use. ## How was this patch tested? Technically I could add an end-to-end test to verify this one-line change, but it seemed too trivial to me. Author: Reynold Xin <r...@databricks.com> Closes #16300 from rxin/SPARK-18892.
