Implemented the plumbing for paint worklets
<!-- Please describe your changes on the following line: -->
This PR implements the plumbing for paint worklets:
* Adding CSS values for paint worklets.
* Implementing a skeleton for the `PaintWorkletGlobalScope` webidl.
* Implementing an executor for paint worklet tasks, and passing it from script to layout.
* Building the display list items for paint worklet images.
This PR does not implement registering or calling paint worklets in JS.
Before it merges, this PR needs a reftest added for basic paint worklet functionality.

Separate waking the event loop, from communicating with Compositor
<!-- Please describe your changes on the following line: -->
@paulrouget first step of #15934, Glutin only for now, please take a look...
If this makes sense, I will also update the code for ports other than Glutin...
One question: one do I add the `warn!` macro to `servolib`? Also perhaps we would also want to add `box`, since I had to switch to using `Box::new`...

Increase the size of the style sharing cache to 31.
Still a lot of guesswork here, but this does seem to get us better sharing. See

stylo: Bug 1335998 - Handle interpolation and accumulation of mismatched transform lists
These are the interdependent patches of Bug 1335998. We want to do interpolation and accumulation for mismatched transform lists, so introduce ComputedOperation::InterpolateMatrix and ComputedOperation::Accumulation. Both arms store the from_list and to_list, and resolve them until we have the layout information. For the Servo part, we haven't implemented how to read the transform lists in layout/fragment.rs, but I think it would be easy. (related issue #13267)

We convert ComputedOperation::{Accumulate, Interpolate}Matrix into gecko type
not on the main thread, so we cannot use nsCSSValueList_heap (which is not
thread safe so we cannot create it and destroy it on different threads).
Therefore, we use nsCSSValueSharedList to represent the cloned
from_list/to_list. In this patch, we also implement the reversing way,
i.e. Convert eCSSKeyword_{accumulate, interpolate}matrix into
{Accumulate, Interpolate}Matrix.
If we set the composite operation to accumulate, we may need to accumulate two
mismatched transform lists, and then to interpolate them. In order to
accumulate two mismatched transform lists, we also need the reference
box information, so use the same idea as that for interpolation. i.e.
use AccmulateMatrix to store it temporarily, and convert it into matrix
later.
We use this arm to store the interpolated result of two mismatched
transform lists, and we resolve it until we know the reference box size
(on Gecko side). The conversion from ComputedOperation::InterpolateMatrix
to eCSSKeyword_interpolatematrix will be implemented later in this patch series.
The pref `webgl.testing.context_creation_error` will cause creation of a new WebGLRenderingContext to fail, iff set to true.
Also update test expectation of `context_creation_error.html` to pass.
Ged rid of libfontconfig in Android
Libfontconfig dependency is causing huge startup times in Android (20 seconds on each page load!). On other platforms fontconfig caches are already available or can be prebuilt on installation scripts, but this can't be done on Android. Updating libfontconfig dependency doesn't fix the problem either.
This PR gets rid of libfontconfig in Android. It queries available fonts and variations from Android System font configuration files. Android doesn't provide an API to query system fonts until Android O (which is very far from the minimum API right now...)
