Liang-Chi Hsieh 2c9597f88f [SPARK-27701][SQL] Extend NestedColumnAliasing to general nested field cases including GetArrayStructField ... ## What changes were proposed in this pull request? `NestedColumnAliasing` rule covers `GetStructField` only, currently. It means that some nested field extraction expressions aren't pruned. For example, if only accessing a nested field in an array of struct (`GetArrayStructFields`), this column isn't pruned. This patch extends the rule to cover general nested field cases, including `GetArrayStructFields`. ## How was this patch tested? Added tests. Closes #24599 from viirya/nested-pruning-extract-value.
