This patch implements the following changes:
- Only check for the toplevel/sublevel part of the mime type when
deciding if it's a js or css resource, ignoring the mime parameters.
- Fix the wpt tests that did not escape url parameters properly and
also used an invalid syntax for the mime parameter.
- Update the wpt manifest.
<!-- Please describe your changes on the following line: -->
Add check for bad ports to http_fetch(), return NetworkError::Internal if bad port/schema combination is seen.
