This fixes #3970

In this PR we are validating the executor timezone. If the driver timezone is supported to run on GPU, then we check if the executor timezone is also same. If executor timezone is different then we throw exception with the message to set executor timezone to match driver time zone.
Since it is reproducible only in cluster setup, I haven't added any tests. Verified this PR by running orc_test.py in YARN cluster.

Thanks @tgravescs for helping in debugging this issue.

CI failure due to this error:

Error: :35:22.567Z] [ERROR] [Error] /home/jenkins/agent/workspace/jenkins-rapids_premerge-github-3317/sql-plugin/src/main/scala/org/apache/spark/sql/rapids/GpuOrcFileFormat.scala:132: not found: value OrcFileFormat
Error: 1-19T00:35:22.569Z] [ERROR] one error found

I will upmerge and restart CI once #4139 gets merged which has the fix for above error.
