Finalize l10n_packager drush command

In the D9 version, a "release" can be either an l10n_server_release or an l10n_packager_release entity. In the D7 version, l10n_packager_release_set_branch applies to what would be an l10n_server_release entity, whereas l10n_packager_release_check would be l10n_packager_release. What is the point of the first call in this context anyway? How could this be solved, according to you?

@sanduhrs declared some arguments (force and all) which do not exist in the D7 version. What are we supposed to do?

I am not exactly sure what other two commands (create/queue) are for BTW.

Apparently sanduhrs wanted to use the queue API in l10n_packager_cron(). I commented the code in the meantime until we make a decision on this point.

Postponing until migrations are a thing, so we can test on real data.

Discussed with @fmb during Barcamp Perpignan

Keep 1 to 1 port for now

Remove dead code:
- new options: force, all
- new (not implemented) drush commands: create, queue

As queue is not implemented yet, prevent to introduce extra complexity (release, unprocessed items)
D7 was not using it, so it should work https://git.drupalcode.org/project/l10n_server/-/blob/7.x-1.x/l10n_packa...

Make sure that it works like this
- Check database query with D7 one
- Set the source of truth
- Create test

Working on it

Thanks @colorfield!
