Kazuaki Ishizaki ada28f2595 [SPARK-23933][SQL] Add map_from_arrays function
## What changes were proposed in this pull request?

The PR adds the SQL function `map_from_arrays`. The behavior of the function is based on Presto's `map`. Since SparkSQL already had a `map` function, we prepared the different name for this behavior.

This function returns returns a map from a pair of arrays for keys and values.

## How was this patch tested?

Added UTs
