http://www.robohornet.org gives a score of 101.36 on master, and 102.68 with this PR. The latter is slightly better, but probably within noise level. So it looks like this PR does not affect DOM performance.
This is expected since `Box::new` is defined as:
```rust
impl<T> Box<T> {
#[inline(always)]
pub fn new(x: T) -> Box<T> {
box x
}
}
```
With inlining, it should compile to the same as box syntax.

The elephant 🐘 (not PHP's) still remains in the room: `Rc<Promise>` shouldn't require `#[allow(unrooted_must_root)]`.

<!-- Please describe your changes on the following line: -->
Servo WebVR implementation started when WebVR spec 1.2 was about to be released. 1.2 API included some minor breaking changes from spec 1.1 in order to improve the support of the API in WebWorkers.
But eventually the WebVR committee decided not to release 1.2 and make it a major version number with a lot more changes. WebVR API 2.0 is still under heavy churn.
This PR removes the WebVR changes that non-released 1.2 version introduced to support full WebVR 1.1 spec.
I pushed some GC fixes in a separate commit. See https://github.com/servo/servo/issues/17076 and https://github.com/servo/rust-mozjs/issues/351

<!-- Either: -->
- [ ] There are tests for these changes OR
- [X] These changes do not require tests because : current gamepad tests are manual (https://github.com/w3c/web-platform-tests/tree/master/gamepad). There is a open issue about the best way to test WebVR/Gamepad without real devices https://github.com/w3c/webvr/issues/187. We'll work on the testing suite & mock devices/data on a separate issue.

WebVR API Implementation with HTC Vive support on Windows. The current implementations only enables the WebVR support on Windows. In other platforms the API is available on JavaScript but navigator.vr.getDisplays() returns an empty array. This will change when we add support for more VR providers and platforms ;)

Proprietary openvr.dll must be copied next to servo.exe in order to test on HTC Vive (https://github.com/ValveSoftware/openvr/tree/master/bin/win64) I have added some of the official WebVR samples for testing. Switch on your headset and run:
mach run tests/html/webvr/room-scale.html
