### What changes were proposed in this pull request? This PR aims to show a deprecation warning on two-parameter TRIM/LTRIM/RTRIM function usages based on the community decision. - https://lists.apache.org/thread.html/r48b6c2596ab06206b7b7fd4bbafd4099dccd4e2cf9801aaa9034c418%40%3Cdev.spark.apache.org%3E ### Why are the changes needed? For backward compatibility, SPARK-28093 is reverted. However, from Apache Spark 3.0.0, we should give a safe guideline to use SQL syntax instead of the esoteric function signatures. ### Does this PR introduce any user-facing change? Yes. This shows a directional warning. ### How was this patch tested? Pass the Jenkins with a newly added test case. Closes #27643 from dongjoon-hyun/SPARK-30886.
