multiple facets with one apply button - Facets 3

This is a Facets 3 Ported version of https://www.drupal.org/files/issues/2020-09-09/facets-3013702-34.patch → . The related issue have a lot more work, I just pick this old patch version because its simplicity and because don't need the facets_summary module.

The above patch no longer applies to the latest dev versions, here is an update that should work.

I've updated the patch, also added the apply button to the dropdown facet.

Forgot to make the label translatable.
