What?

We're using the GP_Locales for various purposes on WordPress.org, and in one of them I noticed some irregularities in some country_codes listed.

• de_AT lists the country code as de, instead of at
• fa_AF doesn't list the country code, but includes the country specifier in the locale, so might as well define country_code.

Notably, I've ignored the following locales, which specify a country in the WP locale:

• fa_IR (Persian) - appears to just be the root Persian language, fa_AF above is a variant of Persian?
• ms_MY (Malay) - Is the only Malay included, so no need to specify that it's the Malaysian Malay.

Why?

Although not the intended use-cases, this had resulted in:

• de_DE and de_AT being localised to de rather than de and at. de_CH is correctly set to ch.
• fa_AF being listed as just fa as it doesn't specify the country code.

How?
