Android-library module, drawn from the byte-identical AppLanguage in Agendula
and Calendula: read the shipped languages from res/xml/locales_config.xml,
get/set the applied language via AppCompatDelegate, and render each language's
autonym. The locales_config resource id is now a parameter, so the module is
app-agnostic. appcompat only, no Compose.
