SUMMARY

This PR is based on #22169 and fixes some issues with the native filters dropdown button:

• Style tweaks
• Adds icon and label
• Adds logic to identify the active filters in the dropdown and update badge to reflect
• Forces button to appear even when container has no overflowing items if custom dropdown content is inserted
• Fixes an issue where filters/dividers would appear in horizontal overflow view when not in the overflow dropdown

Note: there are still some issues with getting the component to resize correctly, but those will be addressed in a future PR.

`More filters` appears even when there's nothing overflowing and there are no filters out of scope

1. I pushed a fix for the issue with empty content in the dropdown. Now the dropdown button won't display if the menu is empty
2. Not really related to this PR, but after discussion with @kasiazjc I removed the style overrides for Add/Edit filter button in horizontal mode. It was implemented as in designs, but it was inconsistent with the vertical version. Now both vertical and horizontal buttons look the same.
