Added UPDATE support to EnumerableTableModify. Generates code that calls ExtendedEnumerable.update, which is new, and scans the destination list to apply updates.

Thank you for your contribution! Please refer to point four of the PR template and make adjustments accordingly.

4. CRITICAL CONSISTENCY RULE
   The following three items MUST match exactly in wording and meaning:
   (A) The Jira Issue Title
   (B) This Pull Request Title
   (C) Your Git Commit Message

   Format: [CALCITE-XXXX] <Description>
   Example: [CALCITE-0000] Add IF NOT EXISTS clause to CREATE TABLE

   Guidelines for a good Title:
   - Illustrate using SQL keywords (in ALL-CAPS) rather than Java method names.
   - Focus on the specification and user experience, not the implementation.
   - Make it clear whether it is a bug or a feature.
   - Use words like "should" to indicate desired behavior vs. current behavior (e.g., "Validator should not close model file").
