Bug 1732047 [wpt PR 30893] - Add WPT tests for <script type=webbundle>, a=testonly

Automatic update from web-platform-tests
Add WPT tests for <script type=webbundle>

This CL refactors some WPT tests for <link rel=webbundle>, and
introduces WPT tests for <script type=webbundle> by extracting
common codes into -test.js files.
