Pull request overview
This PR fixes a memory leak issue (T1317109) that occurs when PivotGridDataSource is reassigned. The fix ensures that internal DataSource instances within store objects are properly disposed when the PivotGridDataSource itself is disposed.
Changes:
- Added
dispose()methods to LocalStore, RemoteStore, and XmlaStore classes - Modified PivotGridDataSource.dispose() to call the store's dispose method
- Added tests to verify that LocalStore and RemoteStore dispose their internal DataSource instances
- Improved code formatting with consistent indentation in data_source.ts

| File | Description |
|---|---|
| packages/devextreme/testing/tests/DevExpress.ui.widgets.pivotGrid/dataSource_bundled.tests.js | Added two tests to verify that PivotGridDataSource.dispose() properly disposes the internal DataSource in both LocalStore and RemoteStore |
| packages/devextreme/js/__internal/grids/pivot_grid/xmla_store/m_xmla_store.ts | Added empty dispose() method to XmlaStore for interface consistency (XmlaStore doesn't maintain internal DataSource) |
| packages/devextreme/js/__internal/grids/pivot_grid/remote_store/m_remote_store.ts | Added dispose() method that disposes the internal _dataSource using optional chaining for null safety |
| packages/devextreme/js/__internal/grids/pivot_grid/local_store/m_local_store.ts | Added dispose() method that disposes the internal _dataSource using optional chaining for null safety; also removed unnecessary eslint-disable comment |
| packages/devextreme/js/__internal/grids/pivot_grid/data_source/m_data_source.ts | Updated dispose() to call store's dispose method; improved code formatting with consistent indentation |

This fireEvent('disposing') call is redundant because it's already executed in the [same method] base method (

All these nullification assignments (= null;) appear to be unnecessary. I ran the tests and everything works fine without them.
