[Workspace] Filter left nav menu according to the current workspace

[ruanyl]

Is your feature request related to a problem? Please describe.

With the introduction of workspaces, users can now configure different sets of features/plugins to be displayed within each workspace. However, the current implementation of the left navigation menu in OpenSearch Dashboards presents all available features, which doesn't align with the workspace-specific configurations.

Describe the solution you'd like

To address this issue, we propose leverage the existing linkUpdaters$ observable in the NavLinksService. It would require a small refactor so that it can support custom link filters.

Use application.registerAppUpdater to update the apps to inaccessible if the workspace doesn't have the apps configured.

Describe alternatives you've considered
