[Security Solution][Investigations] - Add session field to highlighted fields table

[michaelolo24]

In lieu of the work necessary to provide full session information for a given alert, we would like to add the process.entry_leader.entity_id field to the highlighted fields table in the alert flyout to provide users with related alerts based on that session id which they can then investigate upon in timeline.

This is what it would look like @paulewing. I remember you wanted to potentially add a different label to the entry leader row.

@michaelolo24 is ticket still relevant, now that we have custom highlighted fields? I feel like we might be able to close it?
