[GS] Add Security Solution deep links to navigational search

[joshdover]

Meta issue: #72680

In #83380 we added support for applications to include a searchDeepLinks property on their core.application.register call which feeds into the navigational search feature.

Security Solution apps should add this property to add deep links for their key locations to search. In most cases, this should be adding an array with the name of the location and a URL path to the route in your app. See the documentation for this API for more info. Some things to consider:

• The title for each link should be localized
• The path for each link should be relative to your application's appRoute. Base path does not need to be included.
• If there are locations that are only conditionally available (for example, due to licensing or feature controls), you can utilize the appUpdater$ API. See the example in the Stack Management app.

@spong Any update here on when this may be scheduled?

I spoke with @oatkiller and he mentioned @kqualters-elastic is looking at some of this for 7.12 (exposing security entities), but the rest might bleed over to 7.13.

Most of these locations should now be searchable in Kibana when license level is appropriate. The tabs on the manage detections page are missing however, as those tabs are not their own route like in other places in SIEM, the active tab is instead tracked in application state.

Shouldn't be much effort to add search entries here https://github.com/elastic/kibana/blob/master/x-pack/plugins/security_solution/public/app/search/index.ts#L20 if those tabs are ever linked to the url.

Thanks @kqualters-elastic! For future reference, here's the issue I created for adding deep links into those views within Detections: #92345
