Make cross-origin canvas drawing tests use a same-origin redirect.
These tests either pass or maintain existing known failures in Firefox and Chrome, and expose the problem in our current implementation that #15887 is addressing.

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.
Don't create a new XHR until the previous one is complete.
This test often times out when run under rr, because the event loop gets flooded with timer events that initiate XHRs before the previous XHR has completed. Additionally, we're running the event handler up to three times per XHR, which is just silly.

Support origins in CSSOM stylesheets
<!-- Please describe your changes on the following line: -->
I still need to pass the origin clean flag to constructors. `style::stylesheets::Stylesheet` has an origin field but I don't think that's relevant.
I can get href in htmllinkelement.rs like this:
```rust
let element = self.upcast::<Element>();
let href = element.get_string_attribute(&local_name!("href"));
```
But I'm not sure how to proceed after here.
@Manishearth any opinions?

The spec says that a script must be immediately prepared whenever "the script element
is connected and a node or document fragment is inserted into the script element,
after any script elements inserted at that time."
