[Security Solution] Move Endpoint details flyout and related middleware to their own functions

[academo]

Summary

This PR is a continuation to #107632

Even though there seem to be many changes, this PR doesn't change any business logic. It moves things from a file to other and adds a new redux action to later be used.

Tests will be added for this new component after is moved to common components in the following refactor PR.

What in the past was a component like this:

<Flyout>
  <Header>
  <Content>
  <Foorter>
  <Tabs>
</Flyout>

turns to be:

<Flyout>
	<DetailsContent>
</Flyout>

and the DetailsContent would be:

<Header>
<Content>
<Foorter>
<Tabs>

What had been done:

• The endpoint hosts middleware had been further refactor to split the section that loads an endpoint details and the ingest policies
• The Endpoint details flyout component doesn't have visual components anymore. Now it only reads the endpoint id from the url and dispatch an action to load the endpoint details data.
• The Endpoint details component had been detached from URL query parameters. It still displays data based on the redux store.

TODO in upcoming PRs:

• Detach the internal policy flyout content from queryParameters (make them optional)
• Move the endpoint details component (non-flyout) to common components
• Invoke the endpoint details component from the timeline view.
