Fix blank page layout after navigation (#17340)

Until now, it wasn’t possible to navigate between page layouts.
Dashboards don’t contain links to other dashboards. With record page
layouts, however, a page layout can now contain a link to another page
layout. If the user opens a record in the side panel and then clicks a
link to another record, the current page layout is replaced with the
page layout for the clicked record.

In this scenario, the `PageLayoutRenderer` component is not remounted.
As a result, the `isInitialized` state was not reset to `false`, and the
corresponding initialization `useEffect` was not triggered again.

All page layout states are component states bound to
`PageLayoutComponentInstanceContext`. For example, after navigating to
another record, `pageLayoutPersistedComponentState` was actually
`undefined` because the context's `instanceId` had changed.

Replacing the `isInitialized` state with a component state fixes the bug
and is consistent with the existing pattern of using component states to
store everything related to page layouts.
