[Enhance] Implement Registration Function for Dynamic NavLink Management

[willie-hung]

Problem statement

Currently, the management of active navigation links relies on hard-coded logic. This approach limits flexibility, as seen in the current implementation:
https://github.com/opensearch-project/OpenSearch-Dashboards/blob/478176ab553045e7e8e7b515f6c55b46e2bff2d4/src/core/public/chrome/ui/header/nav_link.tsx#L42C1-L48C70

This issue is also discussed in PR #5432 and Issue #5226.

Proposed solution

To enhance flexibility and allow for more dynamic management of navigation links, a registration function should be implemented. This function will enable individual apps within OpenSearch Dashboards to control their active navigation links.

Just a further note here that these nav behaviors are very similar to breadcrumb functionality, so as much as possible we should follow the existing breadcrumb registration patterns.
