[Security Solution][Entity details] - move prevalence related hooks to flyout folder

[PhilippeOberti]

Summary

This PR continues the effort in removing all old flyout components, hooks and utils functions. It moves all the code related to prevalence and process tree for analyzer and other components from commone folders to the alert details expandable flyout folder

The goal of this PR is to:

• move the code and update the imports
• add unit tests if they were not present

The purpose of the PR was never to full refactor the code, so things that aren't necessarily super clean might still be present.

No UI changes should be visible whatsoever!

Checklist

• Unit or functional tests were updated or added to match the most common scenarios
