Function mozjs_sys::jsapi::JS::IterateRealmsWithPrincipals

pub unsafe extern "C" fn IterateRealmsWithPrincipals(
    cx: *mut JSContext,
    principals: *mut JSPrincipals,
    data: *mut c_void,
    realmCallback: IterateRealmCallback
)

Like IterateRealms, but only call the callback for realms using |principals|.
