[feature]: Region can be optional or required

[sirugh]

Is your feature request related to a problem? Please describe. The region input field is currently always required although some countries do not use them or require them.

https://github.com/magento/pwa-studio/pull/2659#issuecomment-682238724

If someone wants to make the region field optional they have to duplicate the component just to remove the validate prop on the region field.

Describe the solution you'd like

1. Allow for configuration to inform the UI whether region is required or not.
2. Surface this configuration in a GQL query, probably the countries query

Describe alternatives you've considered

One alternative would be to remove the validate prop on the region field implementations. It would then fall to the user to submit the form to find out if the region is required or not. I would prefer not to do this.
