[Enterprise Search] Move Search Applications to Applications module (#155805)

## Summary

Move Search Applications pages from the Content module to a new
Applications module in `enterprise_search`.

When initially implementing engines behind a feature flag in 8.7 it was
decided to add the pages to the content application to make it easier to
share components and expedite development. But as we're trying to land
Search Applications in 8.8 (formerly engines) we've decided they need to
be in there own plugin public application for several reasons, but the
driving one is to add a global navigation option for Search
Applications. Additionally we get to render search_applications under a
better URL than `content/engines`.

### Screenshots

Search Applications added to global collapsible navigation:

URL and Breadcrumbs updated
