Takuya UESHIN 568055da93 [SPARK-23054][SQL][PYSPARK][FOLLOWUP] Use sqlType casting when casting PythonUserDefinedType to String. 
## What changes were proposed in this pull request?

This is a follow-up of #20246.

If a UDT in Python doesn't have its corresponding Scala UDT, cast to string will be the raw string of the internal value, e.g. `"org.apache.spark.sql.catalyst.expressions.UnsafeArrayDataxxxxxxxx"` if the internal type is `ArrayType`.

This pr fixes it by using its `sqlType` casting.

## How was this patch tested?

Added a test and existing tests.

Closes #20306 from ueshin/issues/SPARK-23054/fup1.
