chore: support mk_MK, cnr_ME & sr_Cyrl_RS (#7941)

Locales have to be described in assets-meta.js so that the respective loaders are created.

message bundle props files exist, but they consist of the english translation, the translations are to be provided by the translation service
CLDRs for the locales don't exist (even in the latest openui5/core version) and only commented entries are added
