fix: IrisGridModelUpdater causes "cannot update during an existing state transition" warning

[ericlln]

IrisGridModelUpdater displays an error/warning in the browser console when

• The reset button is clicked in the organize columns tab in the sidebar of the grid
• A rollup is added to the table using the sidebar tab

These warnings were causing two e2e tests to fail locally. Full logs can be found in the ticket.

Similar to #2249, it looks like the frozenColumns setter in IrisGridModelUpdater was also emitting an event in the render cycle that caused a React warning about the render not being a pure function, because the event triggered a state update in IrisGrid. The setter is now wrapped in useEffect instead of useOnChange so the events are emitted after the render.
