[TASK] Add more consistency to multi record selector

This does a few follow up changes to increase
consistency and allow further use cases.

* Introduce a wrapper class to prevent jumping of
  the multi record selection actions and to unify
  the space between the actions and the record listing

* Introduce new event listener for the actions,
  allowing JavaScript modules to influence the
  display based on their custom logic

* Allow defining the actions multiple times on the
  same page (e.g. above and below the records listing)

* Move "Selection:" label to EXT:core, while using
  it in both, filelist and file selector now
