layout: Partial support for sizing keywords on flex items (#35469)
* Add tests for sizing keywords on flex items

Signed-off-by: Oriol Brufau <obrufau@igalia.com>

* layout: Partial support for sizing keywords on flex items

When a flex item has `flex-basis: auto`, the used `flex-basis` is the
value of the main size property. In that case, if the main size property
was set to keyword, we were always assuming it was `auto`. Now we handle
non-`auto` keywords correctly.

* The status change logic of the `TouchHandler` is changed.
> The `WaitingForScript` state is canceled. TouchAction can be identified
  based on the current touch type and numbers if touch points.
* Sends current event to script thread along with recognized `TouchAction`.
> After dispatch event, script thread sends a `TouchEventProcess(EventResult)`
  message to main thread. If the event is set to `DefaultAllowed`, the
  corresponding `TouchAction` information is added.
* After receiving `DefaultAllowed(TouchAction)` message, main thread executes corresponding action.
> `DefaultPrevented(TouchEventType)` is received. Use `prevent_click` to mark
  that the default `Click` is blocked, and `prevent_move` to mark that the
  default `Scroll` and `Zoom` are blocked. In this way, all TouchActions
  implement preventDefault.

libservo: Expose an OffscreenRenderingContext and use it for servoshell (#35465)
Create a new `RenderingContext` which is used to render to a
`SurfmanRenderingContext`-related offscreen buffer. This allows having a
temporary place to render Servo and then blitting the results to a
subsection of the parent `RenderingContext`.

The goal with this change is to remove the details of how servoshell
renders from the `Compositor` and prepare for the compositor-per-WebView
world.

This splits the logic to resolve the used value of `flex-basis` into its

And then it changes `flex_base_size()` to resolve the provided keywords

Protect create_spanned_slot_based_on_cell_above() against arithmetic underflow (#35437)
`Table::create_spanned_slot_based_on_cell_above()` was performing the
subtraction `self.slots.len() - 2`, which could theoretically result
in underflow if `self.slots.len()` is 0 or 1.

That shouldn't have been possible in practice, but it may be worth
addressing, to improve code robustness. So this patch:
  - Switches to `self.current_y()?.checked_sub(1)?`, which is safe and
    is easier to understand.
  - Moves `create_spanned_slot_based_on_cell_above()` to `TableBuilder`,
    since `current_y()` is there, and the method is only used when
    building the table anyways.
  - Ensures that both callers use `expect()` to assert that the method
    returned a value.

libservo: Expose a single InputEvent type and pass it to script (#35430)
This change exposes a single `InputEvent` type and now there is only a
single delegate method for this `WebViewDelegate::notify_input_event`.

- Clipboard events are now handled as `EditingAction` inpute events. In
  the future this can include things like "Select All", etc.

In addition, many parts of the dance to pass these events can now be
simplified due to this abstraction.

- All forwarded events are handled the same way in the `Constellation`,
  though they may carry an optional hit test (for events that have a
  `point`) which affects which `Pipeline` they are sent to.
- In the `ScriptThread` we now accept these `InputEvents` and use them
  everywhere. Now all "compositor events" are "input events".
- This allows removing several data structures which are no longer
  necessary.
- We no longer inform the embedder when an event was handled by a
  WebView as that was only important for a MDI feature that will
  no longer be so important the full-featured `WebView` API.

script: reset spurious frame counter *only* when reflow is triggered (#35435)
I had applied a review suggestion in the previous PR to combine the
nested conditions, but this is wrong as this meant the spurious frame
callback was getting reset not just when the reflow was triggered by the
callback, but also each time the counter reached the threshold.

The test added in the previous PR also had issues with the upstream WPT
repo's lint checks - `test.step_timeout` should be used instead of the
`setTimeout` function.

This patch fixes the counter update logic and also addresses the linting
issue caught by upstream's linter.

script: fix spurious animation checks to correctly invoke rAF callbacks (#35387)
After running an `rAF` callback, if no new callbacks were registered, we
send a `NoAnimationFramesCallback` to the compositor to stop ticking
animations using video refresh callbacks. This interacts badly with the
mechanism to track spurious animations frames i.e. rAF callbacks that
don't mutate the DOM. Such 'faked' rAF callbacks are triggered by
registering a oneshot timer instead of the compositor callback.

The compositor's refresh callback is never enabled back again once a
non-spurious rAF callback runs and registers a new rAF callback. If the
former callback resets the `spurious_animations_frames` counter, then when
the latter rAF callback runs, it will not schedule a OneShotTimer timer
for any rAF callback that itself registers, since the counter was reset
previously. Hence that third rAF callback that never runs as it relies
on the compsitor's refresh callback, which was disabled previously.

The current logic also doesn't actually recognize spurious animation
frames because the `spurious_animations_frames` counter is updated at
the end of the `run_the_animation_frame_callbacks`, effectively meaning
`was_faking_animation_frames` and `self.is_faking_animation_frames` will
always be the same value but the logic effectively only runs when
`(!was_faking && is_faking)` is true.

This patch fixes the logic to detect spurious animations frames by
moving logic to update the counter to be before the check for spurious
frames. It also ensures that the compositor's refesh callbacks is
re-enabled once we see a non-spurious callback.

libservo: Don't bounce ready-to-present frame notifications to the Constellation (#35369)
Instead of telling the Constellation to tell the embedder that new
frames are ready, have the compositor tell the embedder directly. This
should reduce frame latency. Now, after processing compositor
updates, run any pending `WebView::new_frame_ready` delegate methods.

This change also removes the `refresh` call from the Java interface as
that was the only other place that the compositor was rendering the
WebRender scene outside of event looping spinning. This `refresh` call
was completely unused.

  specifcation -- removing the necessity for an `Insecure` variant of
  the permissions prompt.
- Have all allow/deny type requests in the internal API use an
  `AllowOrDeny` enum for clarity.
- Expose `PermissionsRequest` and `PermissionFeature` data types to the
  API and use them in the delegate method.
- Update both servoshell implementations to use the API.

dom: Always replace unpaired surrogates when handling page text (#35381)
Background:

> JavaScript strings are potentially ill-formed UTF-16 (arbitrary
> Vec<u16>) and can contain unpaired surrogates. Rust’s String type is
> well-formed UTF-8 and can not contain any surrogate. Surrogates are
> never emitted when decoding bytes from the network, but they can sneak
> in through document.write, the Element.innerHtml setter, or other DOM
> APIs.

In 2015, Servo launched an experiment to see if unpaired surrogates
cropped up in page content. That experiment caused Servo to panic if
unpaired surrogates were encountered with a request to report the page
to bug #6564. During that time several pages were reported with unpaired
surrogates, causing Servo to panic. In addition, when running the WPT
tests Servo will never panic due to the `-Z replace-surrogates` option
being passed by the test driver.

Motivation:

After this 10 year experiment, it's clear that unpaired surrogates are a
real concern in page content. Several reports were filed of Servo
panicking after encountering them in real world pages. A complete fix for
this issue would be to somehow maintain unpaired surrogates in the DOM,
but that is a much larger task than simply emitting U+FFD instead of an
unpaired surrogate.

Since it is clear that this kind of content exists, it is better for
Servo to try its best to handle the content rather than crash as
production browsers should not crash due to user content when possible.
In this change, I modify Servo to always replace unpaired surrogates.

It would have been ideal to only crash when debug assertions are
enabled, but debug assertions are enabled by default in release mode --
so this wouldn't be effective for WPT tests.
