Preliminary WebXR support
This implements just enough WebXR to display to 3DOF devices in
immersive mode only.
Couple missing things:
- [ ] Handling reference spaces (even if just supporting eye-level spaces)
- [x] Spec links
- [ ] We enter immersive mode when baseLayer is set, but it seems like
we're supposed to do this when requestSession is called (https://github.com/immersive-web/webxr/issues/453)
- [ ] VR/XR should block less (https://github.com/servo/servo/issues/22505)
- [x] More pref-gating
- [x] `views` is a method instead of an attribute because we don't support FrozenArray
<s>Once I add spec links and pref gating</s> this can be landed as-is for further experimentation.

Instead of per-document. This also allows to reuse this thread-pool if needed
for other stuff, like parallel CSS parsing (#22478), and to share more code with
Gecko, which is always nice.
Initialize iframe viewport immediately
This is probably a significant cause of unstable test results, and it finally bothered me enough to fix it. The solution isn't great for performance (a sync layout query every time a iframe is added to a document), but performance needs to follow correctness.

refactoring with ResourceFetchMetadata
implemented deprecated window.timing functionality
created ResourceTimingListener trait
fixed w3c links in navigation timing
updated include.ini to run resource timing tests on ci
Forward WebDriver CompositionEvent
Dispatch composition events in JS.
Insert characters from composition events to text input.
CompositionEvents currently can only be
created by WebDriver and not by embedders.

Dispatch composition events in JS.

CompositionEvents currently can only be
created by WebDriver and not by embedders.
I moved away from the `Window` struct all the logic to handle task
sources, into a new struct called `TaskManager`. In a happy world, I'd
be able to just have there two functions, of the types:
```rust
fn task_source<T: TaskSource>(&self, name: TaskSourceName) -> Box<T>
fn task_source_with_canceller<T: TaskSource>(&self, name: TaskSourceName)
-> (Box<T>, TaskSourceCanceller)
```
And not so much duplicated code. However, because TaskSource can't be a
trait object (because it has generic type parameters), that's not
possible. Instead, I decided to reduce duplicated logic through macros.
For reasons[1], I have to pass both the name of the function with
canceller and the name of the function without, as I'm not able to
concatenate them in the macro itself. I could probably use
`concat_idents` to create both types already defined and reduce the
amount of arguments by one, but that macro is nightly only. At the same
time, not being able to declare macros inside `impl` forces me to pass
`self` as an argument.
All this makes this solution more verbose than it would be ideally. It
does reduce duplication, but it doesn't reduce the size of the file.

We don't have `window` for `workers`. So, if we use `global.as_window()`
to get the DOMManipulationTaskSource, it will make worker panic.
Instead, we should get the DOMManipulationTaskSource from each own
thread.

Use keyboard-types crate
Have embedders send DOM keys to servo and use a strongly typed KeyboardEvent
from the W3C UI Events spec. All keyboard handling now uses the new types.
Introduce a ShortcutMatcher to recognize key bindings. Shortcuts are now
recognized in a uniform way.
Updated the winit port.
Updated webdriver integration.
part of #20331
What this PR does:
* allow the use non-ASCII keyboards for text input
* decouple keyboard event "key" from "code" (key meaning vs location)
What this PR does not do:
* completely improve keyboard events send from winit and webdriver
* add support for CompositionEvent or IME
Notes:
* The winit embedder does not send keyup events for printable keys (this is a regression)
* keyboard-types is on crates.io because I believe it to be useful outside of servo. If you prefer I can add a copy in this repo.

This will allow the HTMLMediaElement later to get a handle to the
RenderApi for rendering video frames.
At a later time, all media handling should be moved to its own
thread/process that is communicated with via IPC. At that point this
can be removed again.
