[Search][FTR] Solution Nav (#195327)

## Summary

Adding `functional_search` suite with a set of test for the search
solution navigation. But this suite will also grow to test search
solution pages that do not require the enterprise search node.

### Checklist

- [x] [Unit or functional
tests](https://www.elastic.co/guide/en/kibana/master/development-tests.html)
were updated or added to match the most common scenarios
- [x] [Flaky Test
Runner](https://ci-stats.kibana.dev/trigger_flaky_test_runner/1) was
used on any tests changed

(cherry picked from commit 71fd96a)
