Check CSP for javascript: URLs (#36709)

Browse source 
Also update a WPT test to fail-fast if the iframe incorrectly
evaluates the `eval`. Before, it would run into a timeout if
the implementation is correct. Now we reject the promise
when an exception is thrown.

Requires servo/rust-content-security-policy#6
