[mediawiki/extensions/CentralNotice@master] Move short-list helper into a dedicated class

https://gerrit.wikimedia.org/r/833775

I haven't been able to reproduce this locally, but uselang=qqx shows where the data is missing:

AT(comma-separator)CH(comma-separator)DE(comma-separator)LI(and)(word-separator)LU; : ((centralnotice-all-except: ))

Looking at the database with this query,

select * from cn_notices
left join cn_notice_countries on not_id = nc_notice_id
left join cn_notice_regions on not_id = nr_notice_id
where not_name='WikiCon 2022 in Germany';

there are only linked countries, no regions. The countries match the list above.

Reproducing the bug locally is simple, I see. Selecting any combination of countries but not changing the region selection will result in a rendered list like "CH; : (Alle außer )". Deselecting at least one region results in a correct rendering like "CH: (Alle außer UR)".

Problem is fixed on the beta cluster where many campaigns are set with countries and no regions, so previously buggy.

ReleaseTaggerBot added a project: MW-1.40-notes (1.40.0-wmf.3; 2022-09-26).Mon, Sep 26, 16:00

I don't believe this is correct. Can ReleaseTaggerBot be taught about the wmf_deploy branch for CentralNotice?
