LibJS: Add the Intl namespace object :^)

This is the start of implementing ECMA-402 in LibJS, better known as the
ECMAScript Internationalization API.

Much like Temporal this gets its own subdirectory (Runtime/Intl/) as
well as a new C++ namespace (JS::Intl) so we don't have to prefix all
the files and classes with "Intl".
