Global variables do not respect custom scalar constraint

[MiroslavPetrik]

Schema:

module default {

  scalar type Lang extending str {
    constraint one_of("sk", 'en');
  }

  required global i18nLang: Lang {
    default := "sk";
  };

}

Current behavior:

The variable can be set with value not respecting the Lang type.

set global i18nLang := "cz";
OK: SET GLOBAL

Expected behavior:

Instead an error of ConstraintViolationError should be displayed.

ConstraintViolationError: Lang must be one of: ['sk', 'en'].
Details: violated constraint 'std::one_of' on scalar type 'default::Lang'

because similarly, when we set a wrong type, we get:

set global i18nLang := 32;
gel error: ConfigurationError: invalid setting value type for default::i18nLang: 'std::int64' (expecting 'default::Lang')

This would be cool also to have handled in the ui so it won't allow to set invalid values (it will fail early).
