Web UI: Add chrome://test data source for testing JS modules

- Add a test data source that serves files from chrome://test
- Autogenerate HTML responses containing a single
<script type="module"> with src set to a requested JS file at runtime.
Request these responses by preloading
chrome://test?module=JS_TEST_FILE.js
- Remaining dependencies, other than mocha and mocha adapter, can
be imported via the JS test module, instead of using |extraLibraries|.
- Map requests for chrome://test URLs to the appropriate Web UI
controller using a new webuiHost parameter for tests.
