This commit aligns `Headers` to spec. It also removes the now unused 03_dom_iterable.js file. We now pass all relevant `Headers` WPT. We do not implement any sort of header filtering, as we are a server side runtime. This is likely not the most efficient implementation of `Headers` yet. It is however spec compliant. Once all the APIs in the `HTTP` hot loop are correct we can start optimizing them. It is likely that this commit reduces bench throughput temporarily.
