<script type=webbundle>: Resolve a relative URL on the bundle's URL

The explainer PR is: https://github.com/WICG/webpackage/pull/700

One of the gaps between the Subresource Loading with WebBundles and
Bundle Preloading proposals is "how to resolve a relative URL of
resources". The former is using document's base URL, and the latter is
using the bundle's URL. We have to align.

At the era of <link>-based API, using a document's base URL might make
sense because `resources` are specified in the link element's
attribute.

Now we use <script>-based APIs, and `resources` is specified in JSON, so
we no longer have any strong reason to use a document's base URL.

See the spec discussion for details:
