Make country and language two general states

[alexfauquette]

The country and the language of the user should be two distinct state that are shared across all games.

The country should be easily modified. Probably in the header for desktop

Their is now a const [country, setCountry] = useCountry() that can be used every where to access the country. And it can be used to either set the country value in the current page (in URL search params) or globally (in the localestorage) by using setCountry(newCountryCode, 'page' | 'global')

Still have to loop on all games to use this in queries
