Update WebIDL.py
I'm working on getting [attributes on types landed in upstream webidl](https://bugzilla.mozilla.org/show_bug.cgi?id=1359269). In preparation for that, I'd like to update WebIDL.py and deal with all the conflicts first so that updating for that bug is easier.
(This PR doesn't need to be reviewed and landed right now, I can just roll it into the PR for implementing attributes on types, but I suspect it would be easier to land this first)
Probably should squash before landing, the steps are separated out for ease of review.

Add optional annotations for initEvent method of Event interface
Added `optional` and default values to parameters `bubbles` and `cancelable` of `initEvent` of `Event`.
I tried to update test results, but there seem to be no differences at all.
I checked similar code where `optional` is used, and there seems to be no special handling in Rust. If that is not the case with this issue, please let me know and I'll commit more follow-ups.

Use webvr future_frame_data to avoid blocking the WebGL thread
<!-- Please describe your changes on the following line: -->
This PR fixes a potential deadlock caused by the WebGL thread being blocked on a VR device. Rather than blocking on the VR device, it forwards a future to the script thread, and then then script thread blocks.

Converted the #define variable NS_STYLE_FLEX_DIRECTION to an enum class in nsStyleConsts.h and made changes in other files that access it

I want to do this so that I can get rid of Either<>. The reasons for getting rid
of either are multiple:
* It doesn't generate as nice C++ code using cbindgen.
* It isn't that nice to use either from Rust.
* cbindgen has bugs with zero-sized types.
I started using this for ColorOrAuto and a few others, for now.

-moz-tab-size, border-image-outset and border-image-slice.
This is not a particularly interesting patch, just removes some code. We can
remove way more code when a few related properties are also ported.

It's a global object, it doesn't have to be stored in nsFont. Pass it from the
caller like the user font set and co.

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as
anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those.
Can't wait for XUL trees to die.

The reason why we use RelaxedAtomBool is that
ScrollSnapUtils::GetSnapPointForDestination() is called both from the main and
the compositor threads, and the function will have a branch depending on the
pref value.

We already avoid putting styles in the shared style cache for an element that
has animations[1] but if we are doing the initial style of two siblings where
the _second_ has animations applied, there is nothing to stop us from trying to
share with the first (un-animated) element. This patch adds a check to prevent
sharing in that case since sharing style between animated elements is unsound
for the reasons described in [1].
A number of tests including:
testing/web-platform/tests/web-animations/animation-model/animation-types/visibility.html
will fail without this fix once we remove the style flush from
KeyframeEffect::SetKeyframes later in this patch series.

Really sorry for the size of the patch :(
Only intentional behavior change is in the uses of HasLengthAndPercentage(),
where it's easier to do the right thing. The checks that used to check for
(IsCalcUnit() && CalcHasPercentage()) are wrong since bug 957915.
