Add 'inventory' item to Security navigation menu (#204373)

## Summary

Add 'inventory' item to Security navigation menu (either when the
sidebar is expanded and the full navigation menu is shown or when the
sidebar is collapsed and only the Security menu is visible).

### Changeset details

- Render 'inventory' item and enable `/app/security/asset_inventory`
route both conditionally based on feature flag
- Async loading/rendering of AssetInventory main page from within
SecuritySolution plugin
  - Delete unnecessary boilerplate existing in AssetInventory

### Out of scope
- AssetInventory nav sub-menu is skipped until more concrete
requirements are defined on what to do with them

### How to test

Activate the feature flag by adding this line to your local
`kibana.dev.yml`:

```yml
xpack.securitySolution.enableExperimental: ['assetInventoryStoreEnabled']
```

### Checklist

- [x] If a plugin configuration key changed, check if it needs to be
allowlisted in the cloud and added to the [docker
list](https://github.com/elastic/kibana/blob/main/src/dev/build/tasks/os_packages/docker_generator/resources/base/bin/kibana-docker)
- [x] The PR description includes the appropriate Release Notes section,
and the correct `release_note:*` label is applied per the
[guidelines](https://www.elastic.co/guide/en/kibana/master/contributing.html#kibana-release-notes-process)

### Risks

No risks. Navigation item will be added if and only if feature flag is
enabled, which shouldn't happen for end users until development is
completed.
