[Shared UX] Adoption of Shared UX Route component (#150357)

## Summary

This PR removes all imports of Route from react-router-dom and
'@kbn/kibana-react-plugin/public' and instead imports Route from
@kbn/shared-ux-router.

### Context
Based on
https://github.com/elastic/kibana/issues/132629#issue-1243243678 This PR
executes steps 2 - 4:

> 2. To make the transition easier, we want to re-export other
react-router-dom exports alongside the modified' Route'.
> 3. Solutions should start using that Route component in place of the
one from react-router-dom. I.e. replace all occurrences of import { ...
} from 'react-router-dom' with import { ... } from
'@kbn/shared-ux-router'.
> 4. All manual calls to useExecutionContext are not needed anymore and
should be removed.

### Future PR

Looks like this might be getting worked on in:
https://github.com/elastic/kibana/pull/145863 (thanks!)

> Introduce an ESlint rule that ensures that react-router-dom is not
used directly in Kibana and that imports go through the new
@kbn/shared-ux-router package.

This is tangentially accomplished through
https://github.com/elastic/kibana/pull/150340 but only addresses using
Route through @kbn/kibana-react-plugin/public'
