Allow sorting of actions

A hint here:
From what I remember, config structure allows both sorting actions and using same actions with different custom labels and different preliminary configuration so it's pretty powerful (just try editing view config yml manually and `drush cim`). It's the UI that is lacking implementation and I remember additional AJAX requests in the views modal were causing errors when I was working on this. Hopefully that's not an issue anymore.

Ohh, a patch already.. ok.

Patch #4 works! Thanks!

We'll need to separate the configuration logic from the Views field plugin class as it's growing too big and readability is getting worse. I'll get to that next thing when I'll have a bit break from the paid work. If anyone wishes to handle this earlier feel free to reassign.

Patch works, but it adds item "weight" to views config and phpunit is warning about "incorrect schema"

NW then.

Reroll the patch from https://www.drupal.org/project/views_bulk_operations/issues/3319079#comm... to apply against the 4.2.x branch.

The patch applies nicely and does the job.

Please see #9 before marking this as RTBC again.

We don't need to store weight here at all, it's enough to reorder actions in view config.

Otherwise this is great work and it's very close, hopefully someone will fix the config issue sometime soon.

Fixed according to my last comment. No big deal and this'll not hang here forever ;) Thanks all!
