WebVR API Implementation
<!-- Please describe your changes on the following line: -->
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

Move some methods from display_list_builder.rs
These methods are not only used during display list construction, so
they are a better fit for the flow structs themselves. This does
not introduce any behavior change, but should make it easier to fix

Don't inherit all properties for eagerly computed pseudos if there are no matching rules.
<!-- Please describe your changes on the following line: -->
When we resolve style for an eagerly computed pseudo-element, such as an anonymous box, if there are no matching rules we currently just clone the parent's style. We should only do that if `inherit_all` is true, otherwise we should inherit only the inherited properties from the parent.
I was going to use `.unwrap_or_default()` on the result of looking up `precomputed_pseudo_element_decls`, but that didn't seem to work since that map lookup returns a reference and not a `Vec` itself.

Refactor box longhands
<!-- Please describe your changes on the following line: -->
Converted some longhands into `vector_longhand` to reduce some repeated codes.
Also some of longhands with same `SpecifiedValue` and `computed_value::T` changed. Re-exported SpecifiedValue instead of computed_value::T. Normally a computed_value can't have a parse function.
