[SPARK-31849][PYTHON][SQL] Make PySpark SQL exceptions more Pythonic
### What changes were proposed in this pull request?
This PR proposes to make PySpark exception more Pythonic by hiding JVM
stacktrace by default. It can be enabled by turning on
`spark.sql.pyspark.jvmStacktrace.enabled` configuration.
```
Traceback (most recent call last):
...
pyspark.sql.utils.PythonException:
An exception was thrown from Python worker in the executor. The below is
the Python worker stacktrace.
Traceback (most recent call last):
...
```
If this `spark.sql.pyspark.jvmStacktrace.enabled` is enabled, it appends:
```
JVM stacktrace:
org.apache.spark.Exception: ...
...
```
For example, the codes below:
```python
from pyspark.sql.functions import udf
udf
def divide_by_zero(v):
raise v / 0
spark.range(1).select(divide_by_zero("id")).show()
```
will show an error messages that looks like Python exception thrown from
the local.

### Why are the changes needed?
Currently, PySpark exceptions are very unfriendly to Python users with
causing a bunch of JVM stacktrace. See "Python exception message without this
change" above.
### Does this PR introduce _any_ user-facing change?
Yes, it will change the exception message. See the examples above.
### How was this patch tested?
Manually tested by
```bash
./bin/pyspark --conf spark.sql.pyspark.jvmStacktrace.enabled=true
```
and running the examples above.
Closes #28661 from HyukjinKwon/python-debug.
