Move kotlin-stdlib-js project and the sources specific to the current backend to 'stdlib/js-v1' directory, but leave sources that can be shared with the new IR backend in the common 'stdlib/js' location with exception for 'stdlib/js/src/generated', which is used exclusively for current backend. This simplifies sourceset configuration when building stdlib with the new backend.
