A function that gives the available locales

[Natchii59]

Is your feature request related to a problem? Please describe.

No there is no problem. It's just that it's annoying to see the list of available locales rewritten each time.

Describe the solution you'd like

I would like us to be able to retrieve via a function the list of all available locales that we have put in the messages/locales folder.

Describe alternatives you've considered

Write each time an array of strings with the available locales.

You can already achieve this by importing the available locales from a shared module. The list of all locales is currently only known to the middleware, therefore we can't expose this e.g. via the provider anyway.

Hope this helps!
