Closes #3220
Presented empty fields with a notice
Added a function that returns a render method compatible with EuiColumn objects that, if the object is either an empty string or undefined, shows a label stating as such (for now only in Value Name on Registry details).
Also replicated the same functionality for the syscheck.value_name in the FIM Discovery dashboard to address the situation in the issue #3220

Testing
Create a enviroment with at least 1 windows agent with syscheck enabled

  • Any empty fields on the FIM inventory should display the label, one can be easily found in the files inventory for a windows agent.
  • Replacing line 129 in public/kibana-integrations/discover/application/components/table/table.tsx with value={""} will empty all the information displayed in all the extended rows of FIM discovery, checking the syscheck.value_name field should show the label.

All the tables in the Integrity monitoring section that show an empty field now display a label with an icon noting them as empty, to help distinguish them from whitespace strings and to improve the look.

  • The name of this file should be with kebab-case: empty-field-handler.js (if possible we have legacy files with camel case)
  • We use 2 spaces on code style. Maybe you are not using prettier on your IDE.

It was meant to be a td element to match the rest of the cells in the table. Fixed in 97821ec

CR: ❌ Review the suggested changes
Test: ✅
With a window size lower, the cell looks a little strange.

I couldn't get the agent report changes about the registry, so I did the suggested trick in the PR comment to get the event detail field:

Maybe a div or span instead of an HTML related to a table. The td/tr elements are set by the table itself.

I need to redo the test to verify it.
