Implement Gradle flavors for Android VR compilations
<!-- Please describe your changes on the following line: -->
This PR adds support to easily generate Android VR builds. Rust/Java VR dependencies are not added by default.
Default build (No VR support)
```
./mach build --release --android
./mach package --release --android
./mach install --release --android
```
GoogleVR builds (e.g. Daydream)
```
./mach build --release --android --features googlevr
./mach package --release --android --flavor googlevr
./mach install --release --android
```
OculusVR builds (e.g. Gear VR)
```
./mach build --release --android --features oculusvr
./mach package --release --android --flavor oculusvr
./mach install --release --android
```

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.

This will allow us to verify the entire detection pipeline in real nightly
builds, which will give us confidence that real heap corruption will be
detected and reported properly.

The reason the patch in bug 1402285 doesn't work is that we call this function
multiple times with the same element. This fixes it.

stylo: do not handle the fallback discrete animation inside the Animate trait
At present, we do the fallback discrete animation for non-invertible matrices in
ComputedMatrix.animate(). However, according to the spec, we should fallback to
discrete animation for cases like:
1. animation between transform with single non-invertible matrix
2. animation between transform with matched transform functions that have at least
one non-invertible matrix
2. animation between transform with mismatched transform functions that have at
least one non-invertible matrix.
The current implementation only handles the first case.
Moreover, we already have fallback discrete animation procedures in CSS Animation
and Web Animation, so we should be able to not doing any fallback inside the
Animate trait.
In this patch, we let the animation between non-invertible matrices to return Err().
So, we can propagate the Err() to the callers, and let the fallback discrete
animation procedure stay at the Servo_MatrixTransform_Operate, which is ouside
the Animate trait.

Bug 1398393 - Add a way to initialize a cooperative thread in servo.
<!-- Please describe your changes on the following line: -->
Over in [bug 1398393](https://bugzilla.mozilla.org/show_bug.cgi?id=1398393), I found that when we turn Quantum DOM's cooperative threads on, we hit a Servo panic because we assume that we've set some state in the TLD. The cooperative threads currently have no way of doing this without also re-initializing the log module and some other static data. This small patch gives the cooperative threads a way of informing Servo about themselves.

ServoStyleSetSizes now has two uses, one for the Stylist, and one for the UA
cache, and so the patch removes 'Stylist' from the field names.

Fix a panic in Stylo memory reporting.
`MallocSizeOfOps::enclosing_size_of_op` is an `Option<>` type, and the panic in
question is caused by not providing a value in a case where it's needed for
measuring a HashSet.
HashMaps and HashSets are common enough that it makes sense to make
`enclosing_size_of_op` non-optional, which this patch does.

Preserve sourceURL comment on style sheets
In addition to the sourceMappingURL comment, there is a second special
comment, "sourceURL", that can be used to set the "display name" of a
style sheet for developer tools. This name is also used as the base
URL for the source-map URL resolution algorithm. sourceURL is
described here:
https://blog.getfirebug.com/2009/08/11/give-your-eval-a-name-with-sourceurl/
The devtools feature bug is here:
https://bugzilla.mozilla.org/show_bug.cgi?id=880831
This patch changes servo to preserve and expose this value for use in M-C.
