[Stream] Fix callout privileges (elastic#198030)

closes elastic#197044
closes elastic#197988

## 📝  Summary

The PR targets fixing 3 bugs:

1. The callout shouldn't be shown if `Logs Explorer` isn't available,
otherwise the link displayed in the callout will cause a problem. [Fix
here](https://github.com/elastic/kibana/pull/198030/files#diff-8c5f793d1bf0d933c73047f31ded8a5a65f91e4f8d5230fc4e40dfb9b245fec1R66)
2. The callout shouldn't be shown if `Logs Explorer` is available but
the user doesn't have privilege to access it, otherwise we end up in
`Application Not Found` page. [Fix
here](https://github.com/elastic/kibana/pull/198030/files#diff-8c5f793d1bf0d933c73047f31ded8a5a65f91e4f8d5230fc4e40dfb9b245fec1R66)
3. The side nav entry for `Logs Explorer` should be hidden if `Logs
Explorer` is disabled. [Fix
here](https://github.com/elastic/kibana/pull/198030/files#diff-ad4e42fbe4d2a7a99ec5d52fbf127ded12f0efe02a10e3afa0409b40be1f4bcfR397)

(cherry picked from commit 5576316)
