Improve the media tests
This avoids a bunch of timeouts and make running the tests from `/html/semantics/embedded-content/media-elements/` in 25 seconds instead of 47 locally on my machine.
style: Cleanup the animated value setup.
We have three different enums to represent slightly different things. Reuse them
properly, and kill some code in the animated_properties module while at it.

Removed integrity check and test for no-cors requests
Removed Step 30.2 which raised a JS TypeError if the integrity metadata was not empty. I manually ran `new Request("", {"mode" : "no-cors", "integrity" : "not an empty string"});` in servo to validate that the exception no longer arose.
