Make XR/VR presenting code async
Previously we only pretended to be async, we returned promises that were already resolved because we synchronously blocked on the channel.
This:
- Moves XR presentation to session creation (where it belongs, see https://github.com/immersive-web/webxr/issues/453)
- Factors out common presentation code in a way that supports asynchronously resolving promises
- Uses this for `VRDisplay::RequestPresent()` and `XR::RequestSession()`

It does not represent `<length> | <percentage>`, but `<length-percentage>`, so
`LengthOrPercentage` is not the right name.
This patch is totally autogenerated using:
rg 'LengthOrPercentage' servo | cut -d : -f 1 | sort | uniq > files
for file in $(cat files); do sed -i "s#LengthOrPercentage#LengthPercentage#g" $file; done

Implement source for postMessage events
Also make similar-origin iframes access their newly loaded document as soon as the new document is created. This should allow tests that check the event.source property to run correctly.

Taskcluster: run tidy on PRs
Taskcluster: run tasks for PRs from everyone
These tasks should be untrusted, since they run before review. The `repo:github.com/servo/servo:pull-request` role determines what scopes (permissions) those tasks have.
https://tools.taskcluster.net/auth/roles/repo%3Agithub.com%2Fservo%2Fservo%3Apull-request
~For more paranoia, we could run these tasks on entirely separate worker types (machine pools). For now, maybe being careful to to give scopes for any kind of write access is hopefully enough.~
There seems to be no way to disable the "docker-in-docker" feature, which could allow tasks to escalate to root on the host worker. So this uses a separate `servo-docker-untrusted` worker type. To manage cost, these workers are configured with `minCapacity: 0` and to shut down after 2 minutes idle. (This is a trade-off with the latency of spinning up new AWS EC2 instances.)

This is a first step to share LengthOrPercentage representation between Rust and
Gecko.
We need to preserve whether the value came from a calc() expression, for now at
least, since we do different things depending on whether we're calc or not right
now. See https://github.com/w3c/csswg-drafts/issues/3482 and dependent bugs for
example.
That means that the gecko conversion code needs to handle calc() in a bit of an
awkward way until I change it to not be needed (patches for that incoming in the
next few weeks I hope).
I need to add a hack to exclude other things from the PartialEq implementation
because the new conversion code is less lossy than the old one, and we relied on
the lousiness in AnimationValue comparison (in order to start transitions and
such, in [1] for example).
I expect to remove that manual PartialEq implementation as soon as I'm done with
the conversion.
The less lossy conversion does fix a few serialization bugs for animation values
though, like not loosing 0% values in calc() when interpolating lengths and
percentages, see the two modified tests:
* property-types.js
* test_animation_properties.html
