Prevent layout shifts when navigating from links in PSI and other setup notifications on the dashboard

## Feature Description

Following on from the work in https://github.com/google/site-kit-wp/issues/4641, ensure that the lazy-loaded dashboard sections are not loaded while scrolling past them after clicking on the links in the PSI and Idea Hub setup notifications.

This will involve a bit of refactoring of the solution to #4641 in order to make it applicable to the PSI/Idea Hub links in `SetupSuccessBannerNotification`.

## Acceptance criteria

* If a user clicks a link that scrolls them to different content on the page (via an ID/`#hash` link), they haven't moved away from that content by manually scrolling the page, and a layout shift in the content should not shift the page and move them away from the content.

## Implementation Brief

See: https://github.com/google/site-kit-wp/issues/4880#issuecomment-1813040905 for a link to a proof-of-concept branch with a fix.

## Changelog entry

*

Start with assets/js/components/notifications/SetupSuccessBannerNotification.js at the linked PSI and Idea Hub links, then review issue #4641 and the proof-of-concept branch linked in the issue comment. Confirm that navigation to hash-linked content remains stable while lazy-loaded sections change, and verify the acceptance criterion for both notification links.
