[Security Solution] Add VersionPicker component (elastic#188302)

**Partially addresses: elastic#171520

## Summary

This PR adds the `VersionPicker` component ThreeWayDiff UI. This
component is a part of the `ComparisonSide` component ([see it on the
Miro
diagram](https://miro.com/app/board/uXjVK0gqjjQ=/?moveToWidget=3458764594147853908&cot=14)).
`ComparisonSide` will display the read-only diff between two selected
field versions.

These component is not yet connected to the Upgrade flyout. You can view
and test it in Storybook by running `yarn storybook security_solution`
in the root Kibana dir. Go to `http://localhost:9001` once the Storybook
is up and running.
