I am ignoring three tests for now with the Comet configuration. This is only for testing purposes within Comet. I will revert these changes after the PR review.

In the followup PR, I will make SparkScan implement org.apache.comet.parquet.SupportsComet, and then Comet will check the flag in org.apache.comet.parquet.SupportsComet to turn on the native operators. Additionally, Comet will allow conversion from int to long and float to double based on the flag in org.apache.comet.parquet.SupportsComet, which means, these tests will pass after the followup PR.
