HyukjinKwon 41af409b7b [SPARK-35303][PYTHON] Enable pinned thread mode by default 
### What changes were proposed in this pull request?

PySpark added pinned thread mode at https://github.com/apache/spark/pull/24898 to sync Python thread to JVM thread. Previously, one JVM thread could be reused which ends up with messed inheritance hierarchy such as thread local especially when multiple jobs run in parallel. To completely fix this, we should enable this mode by default.

### Why are the changes needed?

To correctly support parallel job submission and management.

### Does this PR introduce _any_ user-facing change?

Yes, now Python thread is mapped to JVM thread one to one.

### How was this patch tested?

Existing tests should cover it.

Closes #32429 from HyukjinKwon/SPARK-35303.
