[RAC] [Security Solution] Hides the Show top <field> action in char…

…t legends (elastic#109566)

## Summary

Fixes <elastic#108910> , which allowed users to launch a new `Top <field>` popover from an existing popover, to infinity (and beyond)

The `Show top <field>` action is now hidden in the `Top <field>` popover's chart legend, and also:

- In the legend items of charts throughout the Security Solution (e.g. on the `Overview` page, and in the `Trend` chart on the `Alerts` page)
- For items in the `Count` aggregation table on the `Alerts` page

## Screenshots

### Before (Top `signal.rule.name` popover)
