Improvements to directory.graphqls to include more configation settings

Problem

To build proper customer address forms, we need to have some additional information.

Solution

I've split this PR in two commits, the first is a copy of the current schema in the magento repository, the second are my modifications on it: https://github.com/magento/architecture/commit/5c8ab137d02c8b36a0d063d56883bdf743e5f3c2

Introduce additional country fields:

• add field to Country type: region_required
• add field to Country type: postcode_required
• add field to Country type: name
• add field to Country type: eu
• deprecate full_name_locale in favor of name
• deprecate full_name_english in favor of name
• add field to StoreConfig type: default_country
• add field to StoreConfig type: allow_optional_state
• adds field docs with sorting information: This should be a nice quality of life improvement for the frontend implementor so they don't have to do this on the frontend.
