Support custom JdbcReadWithPartitionsHelper for Jdbc.ReadWithPartitions

[Abacn]

Fix #31419

String sorting is more complex than integers / datetimes (the field can be alpha-numeric; base64; alphabetic; etc, and other scenarios). The solution here is to support custom JdbcReadWithPartitionsHelper.

In fact, the original implementation #15848 entitled "An any-type implementation for readWithPartitions". It pretty much provided the interface to support any-type for readWithPartitions, but not exposed JdbcReadWithPartitionsHelper as public API.

Are we losing the "readWithPartitions only supports the following types: %s" message if there is no custom helper and type is not supported?

Also, I think partitionColumnType is not a required parameter if custom partitionsHelper is passed. Maybe implement something like this?
