Allow using CORS filtered image responses as WebGL textures
More specifically, this makes the "is this image same origin?" check consider the CORS status of the original response, rather than relying on an overly-strict "is this image's response's URL same-origin with a particular global?" check. To do this, we make the image cache double keyed based on the requested URL as well as the requesting origin, and store the CORS status of the eventual response with the final image that eventually gets sent to the HTMLImageElement consumer.

This patch parametrizes WR to handle OES textures if the incoming
frame wraps one.
It requires the update of servo-media package and the according
WR parametrization.
There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.

This module adds a structure (WindowGLContext) which holds the
OpenGL parameters that are going to be used by servo-media player
to render video frames using OpenGL.
In order to fill this structure, three new methods were added to
WindowMethods trait. In this patch only the Glutin-based
implementation provides a simple boilerplate.
The WindowGLContext is created in the entry point of libservo, when
the application window is created, and later passed to the
constellation, the pipeline and to the window element in dom, thus
htmlmediaelement has a mean to obtain these parameters via its
window.
