### What problem does this PR solve? Problem Summary: * In MySQL, LOG(col, e) is equivalent to LN(col), where e is Euler’s number (~2.71828). * Currently, MySQL also supports LOG(col) as a shorthand for LOG(col, e) (i.e., natural logarithm). * This conversion replaces LOG(col) with LN(col) when only a single argument is provided. doc: apache/doris-website#2605
