[SPARK-52779][SQL][CONNECT] Support TimeType literal in Connect

dengziming · MaxGekk · commit fac4433f2399 · 2025-07-16T10:23:16.000+02:00
### What changes were proposed in this pull request? Support TimeType literal in Spark Connect. ### Why are the changes needed? Part of SPARK-51162 to introduce TimeType ### Does this PR introduce _any_ user-facing change? Yes, TimeType literals are supported in Connect, we can use functions such as `org.apache.spark.sql.functions.lit()` to pass a time literal. ### How was this patch tested? Added some unit tests. ### Was this patch authored or co-authored using generative AI tooling? No. Closes #51462 from dengziming/SPARK-51162.
