CompositionEvents currently can only be
created by WebDriver and not by embedders.

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.

We use Size2D and Point2D across compositing, constellation and script,
losing the type of pixels we use (DevicePixel, DeviceIndepententPixel
or CSSPixel) along the way, which might lead to bugs like
window.outerHeight not taking into account the page zoom (using
DeviceIndepententPixel instead of CSSPixel).
This fixes a regression caused by the glutin update.
We now are creating EGL contexts in Linux Wayland, instead of X context, so the
GLContextFactory assumption of one GL back-end per platform is broken.
This just works around it, for now, but in general I think not relying on
available WebGL state is a good thing, and we do that already for WebVR anyway.
This allows servo to use the ExternalScrollId API from WebRender fixing
some issues related to duplicate scroll root ids.
Fixes#17176.
Fixes#19287.
Fixes#19648.
When a paint worklet thread takes too long, we would like to move on,
since we have a ~16ms budget for rendering @60fps. At the moment, there
is no provision in the paintworklet spec to signal such timeouts to the
developer. ajeffrey opened an [issue][1] for this, but it got punted to
v2 of the spec. Hence we are silently timing out unresponsive paint
scripts.
The timeout value is chosen to be 10ms by default, and can be overridden
by setting the `dom.worklet.timeout_ms` pref.
In the absence of such a timeout, the reftest in this commit would fail
by timing out the testrunner itself, since the paint script never
returns. From my discussions with ajeffrey, this should do until we spec
out a way to signal timeouts to the script developer.
Since we did not have a better way to trigger a timeout than a busy
waiting loop (which would hog one core of the test machine until the
timeout was reached), we decided to implement a test only blocking
sleep, available to the PaintWorkletGlobalScope. Since
`dom.worklet.enabled` enables worklets in general, we also decided to
have another pref `dom.worklet.blockingsleep.enabled`, which, in
addition to `dom.worklet.enabled`, would be required for the blocking
sleep to be available.
This fixes#17370.

Use WebRender to compute text index on click events
This is the second half of switching over to WebRender for hit testing.
Now that WebRender gives us the location of the hit tested point in the
display item, we can use that to calculate text index.

Servo currently uses `heapsize`, but Stylo/Gecko use `malloc_size_of`.
`malloc_size_of` is better -- it handles various cases that `heapsize` does not
-- so this patch changes Servo to use `malloc_size_of`.
This patch makes the following changes to the `malloc_size_of` crate.
- Adds `MallocSizeOf` trait implementations for numerous types, some built-in
(e.g. `VecDeque`), some external and Servo-only (e.g. `string_cache`).
- Makes `enclosing_size_of_op` optional, because vanilla jemalloc doesn't
support that operation.
- For `HashSet`/`HashMap`, falls back to a computed estimate when
`enclosing_size_of_op` isn't available.
- Adds an extern "C" `malloc_size_of` function that does the actual heap
measurement; this is based on the same functions from the `heapsize` crate.
This patch makes the following changes elsewhere.
- Converts all the uses of `heapsize` to instead use `malloc_size_of`.
- Disables the "heapsize"/"heap_size" feature for the external crates that
provide it.
- Removes the `HeapSizeOf` implementation from `hashglobe`.
- Adds `ignore` annotations to a few `Rc`/`Arc`, because `malloc_size_of`
doesn't derive those types, unlike `heapsize`.
This is the second half of switching over to WebRender for hit testing.
Now that WebRender gives us the location of the hit tested point in the
display item, we can use that to calculate text index.
