[Security Solution][Expandable flyout] - remove unused code (#201477)

## Summary

Some code was added in [this
PR](https://github.com/elastic/kibana/pull/189633) to allow the
expandable flyout to be used in the OneDiscover context. Later on, [this
PR](https://github.com/elastic/kibana/pull/198294) reverted most of the
changes, but some files remained.

This PR cleans up all the files (that I could find) that are now
unnecessary and unused
