Add auto-territory attribute to i18n!

[varphone]

Add a new attribute auto_territory to the i18n!

i18n!("locales", fallback = "en", auto_territory = true);

The new attribute auto_territory for set the auto territory flag, if true t macro will auto fallback to the language territory of the locale when missing, like: zh-SG => zh, if zh still missing, then fallback to the fallback locale.

I think, this may not need to special config, I want to set this fallback logic by default.

Yes, it makes more sense as the default behavior.
