[Security Solution] Unified Timeline - Implement Row Renderers (#180669)

## Summary

Handles Part 1 of  https://github.com/elastic/security-team/issues/8727

1. This PR adds row-renderers to new Unified Timeline.
2.  Additionally, it also makes couple of small fixes below.
- The UnifiedTable was not auto re-sizing columns to fill the screen
space, when a field was removed or added.
- Whenever a columns was removed from the table, a new `search` request
was fired which should not be the case.
- The current optimization makes sure that once a field has been
fetched, it will always be retained and new request won't be fired till
a new field which has not been requested before is added.
    
### Desk Testing

This feature must be enabled with below feature flag:

```yaml
xpack.securitySolution.enableExperimental:
  - unifiedComponentsInTimelineEnabled

```
 
1. Row Renderers.
    - Enabling/Disabling row renderers should work as expected.
- Entities inside Row Renderers should have hover actions working
correctly.

3. Removing a column should not fire a new request.
- ‼️ Please only remove/add columns from unified field list as shown in
the video below. Because removing a column from the table header results
in an infinite loop

4. Removing or adding column should automatically resize the columns to
fit the width of the table
- ‼️ Please only remove/add columns from unified field list as shown in
the video below. Because removing a column from the table header results
in an infinite loop
