With the language and region tags from the EngineTraitsMap the handling of
SearXNG's tags of languages and regions has been normalized and is no longer
a *mystery*. The "languages" became "locales" that are supported by babel and
by this, the update_engine_traits.py can be simplified a lot.
Other code places can be simplified as well, but these simplifications
should (respectively can) only be done when none of the engines work with the
deprecated EngineTraits.supported_languages interface anymore.
This commit replaces searx.languages by searx.sxng_locales and fix the naming of
some names from "language" to "locale" (e.g. language_codes --> sxng_locales).

Implementations of the *traits* of the engines.
Engine's traits are fetched from the origin engine and stored in a JSON file in
the *data folder*. Most often traits are languages and region codes and their
mapping from SearXNG's representation to the representation in the origin search
engine.
To load traits from the persistence::
searx.enginelib.traits.EngineTraitsMap.from_data()
For new traits new properties can be added to the class::
searx.enginelib.traits.EngineTraits
.. hint::
Implementation is downward compatible to the deprecated *supported_languages
method* from the vintage implementation.
The vintage code is tagged as *deprecated* an can be removed when all engines
has been ported to the *traits method*.
