[Privacy Choices] Use a consolidated API to fetch the user ip country code

[Ecarrion]

closes #9845

Why

We found a public WPCom API to get the user's IP country code: https://public-api.wordpress.com/geo/. This PR updates the feature to rely solely on this API for WPCom and non-WPCom users.

How

• Adds a new IPLocationRemote type to fetch and parse from the new endpoint.

• Update the PrivacyBannerPresentationUseCase to:

  • Use the new API as the only source for the ip country code.
  • Not fetch the new API if privacy choices have been saved.
  • Do not rely on the locale at all.

• Removes the now unused ipCountryCode property from the Account type. (I'm glad I didn't save this on core data!)

Demo

WPCom - EU

wpcom-eu.mov

Should we be adding the custom user-agent header with .asURLRequest() here?

Good catch, I totally missed it!
