[SPARK-46064][SQL][SS] Move out EliminateEventTimeWatermark to the an…
…alyzer and change to only take effect on resolved child ### What changes were proposed in this pull request? This PR proposes to move out EliminateEventTimeWatermark to the analyzer (one of the analysis rule), and also make a change to eliminate EventTimeWatermark node only when the child of EventTimeWatermark is "resolved". ### Why are the changes needed? Currently, we apply EliminateEventTimeWatermark immediately when withWatermark is called, which means the rule is applied immediately against the child, regardless whether child is resolved or not. It is not an issue for the usage of DataFrame API initiated by read / readStream, because streaming sources have the flag isStreaming set to true even it is yet resolved. But mix-up of SQL and DataFrame API would expose the issue; we may not know the exact value of isStreaming flag on unresolved node and it is subject to change upon resolution. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? New UTs. ### Was this patch authored or co-authored using generative AI tooling? No. Closes apache#43971 from HeartSaVioR/SPARK-46064.
