This is a backport of https://github.com/apache/spark/commit/02bb0682e68a2ce81f3b98d33649d368da7f2b3d. ## What changes were proposed in this pull request? `WriteableColumnVector` does not close its child column vectors. This can create memory leaks for `OffHeapColumnVector` where we do not clean up the memory allocated by a vectors children. This can be especially bad for string columns (which uses a child byte column vector). ## How was this patch tested? I have updated the existing tests to always use both on-heap and off-heap vectors. Testing and diagnosis was done locally. Author: Herman van Hovell <hvanhovell@databricks.com> Closes #19378 from hvanhovell/SPARK-22143-2.2.
