[SPARK-42595][SQL] Support query inserted partitions after insert data into table when hive.exec.dynamic.partition=true

[haoyanzhang]

What changes were proposed in this pull request?

Introduce spark.hive.exec.dynamic.partition.savePartitions=true (default false) spark.hive.exec.dynamic.partition.savePartitions.tableNamePrefix=hive_dynamic_inserted_partitions
when spark.hive.exec.dynamic.partition.savePartitions=true we save the partitions to the
temporary view $spark.hive.exec.dynamic.partition.savePartitions.tableNamePrefix_$dbName_$tableName

Why are the changes needed?

When hive.exec.dynamic.partition=true and hive.exec.dynamic.partition.mode=nonstrict, we can insert table by sql like 'insert overwrite table aaa partition(dt) select xxxx', of course we can know the partitions inserted into the table by the sql itself, but if we want do something for common use, we need some common way to get the inserted partitions, for example:

spark.sql("insert overwrite table aaa partition(dt) select xxxx")  //insert table
val partitions = getInsertedPartitions()   //need some way to get inserted partitions
monitorInsertedPartitions(partitions)    //do something for common use

This pull request will allow user to get inserted partitions in a common way

Does this PR introduce any user-facing change?

no

How was this patch tested?
