Subject: ava: Generate Locale menu automatically (#4243)

Currently in `MenuMainBarView.axaml` we list all available languages and hardcode the language name with the language key.
It's a bit bad beause if we want to add a new language, we have to edit the `csproj` and the `axaml` with the translated language name and the language code.
I've put all translations in their respective locale files, add code into `MainMenuBarView` constructor to generate the menu automatically. Now we just have to edit the `csproj` if we want to add a new language.
