[ENDPOINT] First version of the trusted apps list. (elastic#76304)

* First version of the trusted apps list.

* Added proper visualisation of OS and Date Created columns.

* Small change in naming in middleware.

* Renamed function to avoid naming confusion.

* Migrated to usage of selectors and memo in list component.

* Added explicit return types.

* Changed to use server schema for service parameter.

* Removed some over generalisation in types.

* Renamed types and properties related to trusted apps page state.

* Renamed types and properties related to trusted apps page state.

* Renamed the action type to be namespaced to trusted apps.

* Merged the exports and declarations in reducer and used constants for defaults.

* Memoization of pagination data structure.

* Used a shared constant for REST API path.

* Improvements and consistency on pagination across tabs.

* Added a bit more typing and used Partial<>

* Made constants readonly and added some useMemo usages.

* Fixed extracting page index from URI.

* Fixed the case of infinite refreshes when there is loading failure (need to rethink a bit conditions when to refresh).

* Resetting state to initial when we navigate away from trusted apps list.

* Fixed mapping page index to the table pagination.

* Changed to using AppAction in reducer.

* Made ServerApiError a default error type for data binding.

* Renamed all types related to data binding to resource state.

* Created index file for state types.

* Fixed parameter extracting code to meet expectations of endpoints list behavior.

* Updated snapshot.

* Changed middleware to only use selectors.

* Added tests for routing.

* Added documentation to the types in async resource state module.

* Added tests for async resource state module.

* Added tests for store selectors.

* Added tests for reducer.

* Moved around imports.

* Added tests for the middleware.

* Added list component tests.

* Removed a redundant function.

* Commiting snapshots.
