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.

Add a sampling profiler
This uses the code already built for the background hang monitor and adds the ability to repeatedly sample all monitored threads. This sampling allows us to generate profiles that we can translate into the format used by https://perf-html.io/, allowing us to benefit from modern Gecko performance tooling.
You can run Servo with `PROFILE_OUTPUT=foo.json` and `SAMPLING_RATE=50` (for example), otherwise these values will default to `samples.json` and 10ms, respectively. To activate the profiler, press cmd+p, and to stop profiling, press cmd+p again. This will the captured samples to be symbolicated, which will take a very long time, and eventually there will be a new JSON profile in the output location.
To create a profile for use by Gecko's tools, run `python etc/profilicate.py path/to/profile.json >gecko_profile.json`, and load `gecko_profile.json` in the https://perf-html.io/ to see something like [this](https://profiler.firefox.com/public/8137e2b11fbb92afb80090bc534fd83015c87ee6/calltree/?globalTrackOrder=0-1&thread=1&v=3);

Make webgl behave better with session history
This prevents the compositor from animating pages that are not actually visible, so pages using webgl do not needlessly impact the performance of the rest of the browser. Additionally, this fixes a problem that was alluded to in [this code](b5228c098b/src/draw_buffer.rs (L282-L285)), causing Servo to delete arbitrary resources when a GC occurred in content that used three.js.

Instead of per-document. This also allows to reuse this thread-pool if needed
for other stuff, like parallel CSS parsing (#22478), and to share more code with
Gecko, which is always nice.
