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

This simplifies sourceset configuration when building stdlib with the new backend.
multiple unnamed arguments represented as value named expression with array initializer
call kind for array in annotation argument should be "array initializer" instead of "method call"
